a3fb655027 mips: boot: add support for self-extracting FIT images (vmlinuz.itb)
Commit c3e2ee6574 ("MIPS: generic: Add support for zboot") added
support for self-extracting images to Generic MIPS. However, the
intended way to boot Generic MIPS kernels is using FIT Images and
UHI boot protocol, but currently there's no way to make self-extracting
FIT Image (only legacy uzImages).
Add a target for this named "vmlinuz.itb", which will consist of
vmlinuz.bin and selected DT blobs. It will allow to have the advantages
of both UHI and self-extracting images.

9d63bcb871 mips: boot: clean up self-extracting targets scenarios
1. All final targets like vmlinuz.{bin,ecoff,srec} etc. should reside in
   $(objtree)/arch/mips/boot, not in the root $(objtree) directory.
   The only file that should be left there is vmlinuz, similar to other
   architectures.
2. Add all the targets to $(targets) variable, so they'll be properly
   accounted by Kbuild. This also allows to remove redundant
   $(clean-files) (which were missing uzImage BTW).
3. Prefix all targets with $(obj)/$(objtree), depending on their
   locations.

Misc: fix the identation of the 'STRIP' quiet message.

195615ecc8 MIPS: Loongson-3: Enable COP2 usage in kernel
Loongson-3's COP2 is Multi-Media coprocessor, it is disabled in kernel
mode by default. However, gslq/gssq (16-bytes load/store instructions)
overrides the instruction format of lwc2/swc2. If we wan't to use gslq/
gssq for optimization in kernel, we should enable COP2 usage in kernel.

Please pay attention that in this patch we only enable COP2 in kernel,
which means it will lose ST0_CU2 when a process go to user space (try
to use COP2 in user space will trigger an exception and then grab COP2,
which is similar to FPU). And as a result, we need to modify the context
switching code because the new scheduled process doesn't contain ST0_CU2
in its THERAD_STATUS probably.

For zboot, we disable gslq/gssq be generated by toolchain.

HT irqs vectors are 8 groups, each group has 32 irqs, Loongson64C CPUs

number of msi vectors of Loongson64G is 192 (32*8 - 64 = 192).

This is an add-on patch to the main SoC Sparx5 series
(Message-ID: <20200513125532.24585-1-lars.povlsen@microchip.com>).

This changes the miim pinctrl function name from "miim1" to "miim" due
to refactoring in the driver, obsoleting the instance number.

The change in the driver was to better fit new platforms, as the
instance number is redundant information. Specifically, support for
the Microchip Sparx5 SoC is being submitted, where this change became
necessary.

This patch brings support for the JZ4780 efuse. Currently it only exposes
a read only access to the entire 8K bits efuse memory and the
ethernet mac address for the davicom dm9000 chip on the CI20 board.

It also changes the nemc ranges definition to give the driver
access to the efuse registers, which are in the middle of the
nemc reg range.

ff2ae607c6 SPDX patches for 5.7-rc1.
Here are 3 SPDX patches for 5.7-rc1.
 
 One fixes up the SPDX tag for a single driver, while the other two go
 through the tree and add SPDX tags for all of the .gitignore files as
 needed.
 
 Nothing too complex, but you will get a merge conflict with your current
 tree, that should be trivial to handle (one file modified by two things,
 one file deleted.)
 
 All 3 of these have been in linux-next for a while, with no reported
 issues other than the merge conflict.

5f2fb52fac kbuild: rename hostprogs-y/always to hostprogs/always-y
In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.

It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.

This commit renames like follows:

  always       ->  always-y
  hostprogs-y  ->  hostprogs

So, scripts/Makefile will look like this:

  always-$(CONFIG_BUILD_BIN2C) += ...
  always-$(CONFIG_KALLSYMS)    += ...
      ...
  hostprogs := $(always-y) $(always-m)

I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.

The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.

c5951e7c8e The main MIPS changes for 5.6:
- Support mremap() for the VDSO, primarily to allow CRIU to restore the
   VDSO to its checkpointed location.
 
 - Restore the MIPS32 cBPF JIT, after having reverted the enablement of
   the eBPF JIT for MIPS32 systems in the 5.5 cycle.
 
 - Improve cop0 counter synchronization behaviour whilst onlining CPUs by
   running with interrupts disabled.
 
 - Better match FPU behaviour when emulating multiply-accumulate
   instructions on pre-r6 systems that implement IEEE754-2008 style MACs.
 
 - Loongson64 kernels now build using the MIPS64r2 ISA, allowing them to
   take advantage of instructions introduced by r2.
 
 - Support for the Ingenic X1000 SoC & the really nice little CU Neo
   development board that's using it.
 
 - Support for WMAC on GARDENA Smart Gateway devices.
 
 - Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in
   preparation for introducing IP35 (Origin 3*) support.
 
 - Various Kconfig & Makefile cleanups.

 - Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
 
 - pte_special() is now supported for some configurations, allowing among

858805b336 kbuild: add $(BASH) to run scripts with bash-extension
CONFIG_SHELL falls back to sh when bash is not installed on the system,
but nobody is testing such a case since bash is usually installed.
So, shell scripts invoked by CONFIG_SHELL are only tested with bash.

It makes it difficult to test whether the hashbang #!/bin/sh is real.
For example, #!/bin/sh in arch/powerpc/kernel/prom_init_check.sh is
false. (I fixed it up)

Besides, some shell scripts invoked by CONFIG_SHELL use bash-extension
and #!/bin/bash is specified as the hashbang, while CONFIG_SHELL may
not always be set to bash.

Probably, the right thing to do is to introduce BASH, which is bash by
default, and always set CONFIG_SHELL to sh. Replace $(CONFIG_SHELL)
with $(BASH) for bash scripts.

If somebody tries to add bash-extension to a #!/bin/sh script, it will
be caught in testing because /bin/sh is a symlink to dash on some major
distributions.

MIPS: qi_lb60: Migrate to devicetree
Move all the platform data to devicetree.

The only bit dropped is the PWM beeper, which requires the PWM driver
to be updated. I figured it's okay to remove it here since it's really
a non-critical device, and it'll be re-introduced soon enough.

The other change is the CS line of the SPI is now set as active low. The
SPI core would have forced "active low" anyway, unless the 'spi-cs-high'
property is set.

In the process of moving to devicetree, we also switched to new drivers:
- We use the simple-audio-card and simple-amplifier drivers instead of
  the custom ASoC code;
- We use the new Ingenic DRM driver coupled with the GiantPlus GPM940B0
  DRM panel driver instead of the old framebuffer driver;
- We use the new jz4780-dma driver instead of the old jz4740-dma one;
- We use the ingenic-nand and jz4740-ecc drivers instead of the old
  jz4740-nand driver;
- We use ingenic-battery instead of jz4740-battery;
- We use iio-hwmon instead of jz4740-hwmon;
- We use ingenic-iio instead of the old jz4740-adc MFD driver.

MIPS: fix build on non-linux hosts
calc_vmlinuz_load_addr.c requires SZ_64K to be defined for alignment
purposes.  It included "../../../../include/linux/sizes.h" to define
that size, however "sizes.h" tries to include <linux/const.h> which
assumes linux system headers.  These may not exist eg. the following
error was encountered when building Linux for OpenWrt under macOS:

In file included from arch/mips/boot/compressed/calc_vmlinuz_load_addr.c:16:
arch/mips/boot/compressed/../../../../include/linux/sizes.h:11:10: fatal error: 'linux/const.h' file not found
         ^~~~~~~~~~

Change makefile to force building on local linux headers instead of
system headers.  Also change eye-watering relative reference in include
file spec.

MIPS: Use lower case for addresses in nexys4ddr.dts
DTC introduced an i2c_bus_reg check in v1.4.7, used since Linux v4.20,
which complains about upper case addresses used in the unit name.

nexys4ddr.dts names an I2C device node "ad7420@4B", leading to:

  arch/mips/boot/dts/xilfpga/nexys4ddr.dts:109.16-112.8: Warning
    (i2c_bus_reg): /i2c@10A00000/ad7420@4B: I2C bus unit address format
    error, expected "4b"

Fix this by switching to lower case addresses throughout the file, as is
*mostly* the case in the file already & fairly standard throughout the
tree.

afa974b771 kbuild: add real-prereqs shorthand for $(filter-out FORCE,$^)
In Kbuild, if_changed and friends must have FORCE as a prerequisite.

Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common
idiom to get the names of all the prerequisites except phony targets.

Add real-prereqs as a shorthand.

Note:
We cannot replace $(filter %.o,$^) in cmd_link_multi-m because $^ may
include auto-generated dependencies from the .*.cmd file when a single
object module is changed into a multi object module. Refer to commit
69ea912fda ("kbuild: remove unneeded link_multi_deps"). I added some
comment to avoid accidental breakage.

img-ascii-lcd driver via device tree. This reduces the amount of
platform code & the img-ascii-lcd driver offers us advantages in terms
of code sharing with other boards & functionality such as changing the
displayed message via sysfs. Defconfigs are untouched because the driver
already defaults y on when CONFIG_MIPS_MALTA=y.

MIPS: Align kernel load address to 64KB
KEXEC needs the new kernel's load address to be aligned on a page
boundary (see sanity_check_segment_list()), but on MIPS the default
vmlinuz load address is only explicitly aligned to 16 bytes.

Since the largest PAGE_SIZE supported by MIPS kernels is 64KB, increase
the alignment calculated by calc_vmlinuz_load_addr to 64KB.

MIPS: Boston: Disable EG20T prefetch
The Intel EG20T Platform Controller Hub used on the MIPS Boston
development board supports prefetching memory to optimize DMA transfers.
Unfortunately for unknown reasons this doesn't work well with some MIPS
CPUs such as the P6600, particularly when using an I/O Coherence Unit
(IOCU) to provide cache-coherent DMA. In these systems it is common for
DMA data to be lost, resulting in broken access to EG20T devices such as
the MMC or SATA controllers.

Support for a DT property to configure the prefetching was added a while
back by commit 549ce8f134 ("misc: pch_phub: Read prefetch value from
device tree if passed") but we never added the DT snippet to make use of
it. Add that now in order to disable the prefetching & fix DMA on the
affected systems.

MIPS: mscc: add DT for Ocelot PCB120
The Ocelot PCB120 evaluation board is different from the PCB123 in that
it has 4 external VSC8584 (or VSC8574) PHYs.

It uses the SoC's second MDIO bus for external PHYs which have a
reversed address on the bus (i.e. PHY4 is on address 3, PHY5 is on
address 2, PHY6 on 1 and PHY7 on 0).

Here is how the PHYs are connected to the switch ports:
port 0: phy0 (internal)
port 1: phy1 (internal)
port 2: phy2 (internal)
port 3: phy3 (internal)
port 4: phy7
port 5: phy4

The Microsemi Ocelot has a set of register for SerDes/switch port muxing
as well as PCIe muxing for a specific SerDes, so let's add the device
and all SerDes in the Device Tree.

d503ac531a kbuild: rename LDFLAGS to KBUILD_LDFLAGS
Commit a0f97e06a4 ("kbuild: enable 'make CFLAGS=...' to add
additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.

Commit 222d394d30 ("kbuild: enable 'make AFLAGS=...' to add
additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.

Commit 06c5040cdb ("kbuild: enable 'make CPPFLAGS=...' to add
additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.

For some reason, LDFLAGS was not renamed.

Using a well-known variable like LDFLAGS may result in accidental
override of the variable.

Kbuild generally uses KBUILD_ prefixed variables for the internally
appended options, so here is one more conversion to sanitize the
naming convention.

I did not touch Makefiles under tools/ since the tools build system
is a different world.

MIPS: boot: fix build rule of vmlinux.its.S
As Documentation/kbuild/makefile.txt says, it is a typical mistake
to forget the FORCE prerequisite for the rule invoked by if_changed.

Add the FORCE to the prerequisite, but it must be filtered-out from
the files passed to the 'cat' command.  Because this rule generates
.vmlinux.its.S.cmd, vmlinux.its.S must be specified as targets so
that the .cmd file is included.

It is true that commit 0f9da844d8 ("MIPS: boot: Define __ASSEMBLY__

defined __ASSEMBLY__ just for textual substitution in arbitrary data.
The file is image tree source in this case, but the purpose of using
CPP is to replace some macros.

MIPS: Fix build with DEBUG_ZBOOT and MACH_JZ4770
The debug definitions were missing for MACH_JZ4770, resulting in a build
failure when DEBUG_ZBOOT was set.

Since the UART addresses are the same across all Ingenic SoCs, we just
use a #ifdef CONFIG_MACH_INGENIC instead of checking for individual
Ingenic SoCs.

Additionally, I added a #define for the UART0 address in-code and
dropped the <asm/mach-jz4740/base.h> include, for the reason that this
include file is slowly being phased out as the whole platform is being
moved to devicetree.

MIPS: vmlinuz: Use generic ashldi3
In preparation for removing some of the MIPS compiler intrinsics from
arch/mips/lib, first update the build of vmlinuz to use the generic
ashldi3 from lib.

Both ashldi3 and bswapsi objects need to be built with different CFLAGS
for inclusion to vmlinuz rather than simply including the object built
for the main kernel image. The objects cannot be built directly from
source, since CONFIG_MODVERSIONS changes cmd_cc_o_c to prevent this.

Split the rule to ship ashldi3 and bswapsi from the relevant source
locations.

These files make no reference to other files in their directory, so the
additional CFLAGS are apparently unnecessary - remove them as well.

MIPS: dts: Avoid unneeded built-in.a in DTS dirs
arch/mips/boot/dts/Makefile collects objects from sub-directories into
built-in.a only when CONFIG_BUILTIN_DTB is enabled. Reflect it also to
the sub-directory Makefiles. This suppresses unneeded built-in.a
creation in arch/mips/boot/dts/*/ directories.

While I am here, I replaced $(patsubst %.dtb, %.dtb.o, $(dtb-y)) with
$(addsuffix .o, $(dtb-y)) to simplify the code a little bit.

7bbaf27d9c zboot: fix stack protector in compressed boot phase
Calling __stack_chk_guard_setup() in decompress_kernel() is too late
that stack checking always fails for decompress_kernel() itself.  So
remove __stack_chk_guard_setup() and initialize __stack_chk_guard before
we call decompress_kernel().

Original code comes from ARM but also used for MIPS and SH, so fix them
together.  If without this fix, compressed booting of these archs will
fail because stack checking is enabled by default (>=4.16).

0f9da844d8 MIPS: boot: Define __ASSEMBLY__ for its.S build
The MIPS %.its.S compiler command did not define __ASSEMBLY__, which meant
when compiler_types.h was added to kconfig.h, unexpected things appeared
(e.g. struct declarations) which should not have been present. As done in
the general %.S compiler command, __ASSEMBLY__ is now included here too.

The failure was:

    Error: arch/mips/boot/vmlinux.gz.its:201.1-2 syntax error
    FATAL ERROR: Unable to parse input tree
    /usr/bin/mkimage: Can't read arch/mips/boot/vmlinux.gz.itb.tmp: Invalid argument

The unit name was 8c00000 but since the reg property is declared as:

  reg = <0x0 0x4c00000 0x1 0xfb400000>;

the unit name should have been instead 4c00000.

MIPS: dts: Remove leading 0x and 0s from bindings notation
Improve the DTS files by removing all the leading "0x" and zeros to fix
the following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading "0x"

and

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} +

For simplicity, two sed expressions were used to solve each warnings
separately.

To make the regex expression more robust a few other issues were
resolved, namely setting unit-address to lower case, and adding a
whitespace before the the opening curly brace:

This is a follow up to commit 4c9847b737 ("dt-bindings: Remove leading
0x from bindings notation")

37cb8e1f8e DeviceTree for 4.15:
- kbuild cleanups and improvements for dtbs
 
 - Code clean-up of overlay code and fixing for some long standing memory
   leak and race condition in applying overlays
 
 - Improvements to DT memory usage making sysfs/kobjects optional and
   skipping unflattening of disabled nodes. This is part of kernel
   tinification efforts.
 
 - Final piece of removing storing the full path for every DT node. The
   prerequisite conversion of printk's to use device_node format
   specifier happened in 4.14.
 
 - Sync with current upstream dtc. This brings additional checks to dtb
   compiling.
 
 - Binding doc tree wide removal of leading 0s from examples
 
 - RTC binding documentation adding missing devices and some
   consolidation of duplicated bindings
 
 - Vendor prefix documentation for nutsboard, Silicon Storage Technology,
   shimafuji, Tecon Microprocessor Technologies, DH electronics GmbH,
   Opal Kelly, and Next Thing

Pull DeviceTree updates from Rob Herring:
 "A bigger diffstat than usual with the kbuild changes and a tree wide
  fix in the binding documentation.

  Summary:

   - kbuild cleanups and improvements for dtbs

   - Code clean-up of overlay code and fixing for some long standing
     memory leak and race condition in applying overlays

   - Improvements to DT memory usage making sysfs/kobjects optional and
     skipping unflattening of disabled nodes. This is part of kernel
     tinification efforts.

   - Final piece of removing storing the full path for every DT node.
     The prerequisite conversion of printk's to use device_node format
     specifier happened in 4.14.

   - Sync with current upstream dtc. This brings additional checks to
     dtb compiling.

   - Binding doc tree wide removal of leading 0s from examples

   - RTC binding documentation adding missing devices and some
     consolidation of duplicated bindings

   - Vendor prefix documentation for nutsboard, Silicon Storage
     Technology, shimafuji, Tecon Microprocessor Technologies, DH
     electronics GmbH, Opal Kelly, and Next Thing"

7e7962dd1a kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.lib
If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each
DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from
the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile.
It could be a race problem when building DTBS in parallel.

Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor
sub-directories, so this broke when Broadcom added one more hierarchy
in arch/arm64/boot/dts/broadcom/<soc>/.

One idea to fix the issues in a clean way is to move DTB handling
to Kbuild core scripts.  Makefile.dtbinst already recognizes dtb-y
natively, so it should not hurt to do so.

Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is
enabled.  All clutter things in Makefiles go away.

As a bonus clean-up, I also removed dts-dirs.  Just use subdir-y
directly to traverse sub-directories.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

6e62a88802 MIPS: generic: Support MIPS Boston development boards
Add support for the MIPS Boston development board to generic kernels,
which essentially amounts to:

  - Adding the device tree source for the MIPS Boston board.

  - Adding a Kconfig fragment which enables the appropriate drivers for
    the MIPS Boston board.

With these changes in place generic kernels will support the board by
default, and kernels with only the drivers needed for Boston enabled can
be configured by setting BOARDS=boston during configuration. For
example:

  $ make ARCH=mips 64r6el_defconfig BOARDS=boston

d3f616346d MIPS: SEAD-3: Fix GIC interrupt specifiers
The various interrupt specifiers in the device tree are not in a valid
format for the MIPS GIC interrupt controller binding. Where each
interrupt should provide 3 values - GIC_LOCAL or GIC_SHARED, the
pin number & the type of interrupt - the device tree was only providing
the pin number. This causes interrupts for those devices to not be used
when a GIC is present. SEAD-3 systems without a GIC are unaffected since
the DT fixup code generates interrupt specifiers that are valid for the
CPU interrupt controller.

Fix this by adding the GIC_SHARED & IRQ_TYPE_LEVEL_HIGH values to each
interrupt specifier.

fbdc674ba3 MIPS: SEAD-3: Set interrupt-parent per-device, not at root node
The SEAD-3 board may be configured with or without a MIPS Global
Interrupt Controller (GIC). Because of this we have a device tree with a
default case of a GIC present, and code to fixup the device tree based
upon a configuration register that indicates the presence of the GIC.

In order to keep this DT fixup code simple, the interrupt-parent
property was specified at the root node of the SEAD-3 DT, allowing the
fixup code to simply change this property to the phandle of the CPU
interrupt controller if a GIC is not present & affect all
interrupt-using devices at once. This however causes a problem if we do
have a GIC & the device tree is used as-is, because the interrupt-parent
property of the root node applies to the CPU interrupt controller node.
This causes a cycle when of_irq_init() attempts to probe interrupt
controllers in order and boots fail due to a lack of configured
interrupts, with this message printed on the kernel console:

[    0.000000] OF: of_irq_init: children remain, but no parents

Fix this by removing the interrupt-parent property from the DT root node
& instead setting it for each device which uses interrupts, ensuring
that the CPU interrupt controller node has no interrupt-parent &
allowing of_irq_init() to identify it as the root interrupt controller.

Name aliases in the SEAD-3 device tree serial0 & serial1, rather than
uart0 & uart1. This allows the core serial code to make use of the
aliases to ensure that the UARTs are consistently numbered as expected
rather than having the numbering depend upon probe order.

When translating YAMON-provided serial configuration to a device tree
stdout-path property adjust accordingly, such that we continue to
reference a valid alias.

d5d332d3f7 devicetree: Move include prefixes from arch to separate directory
We use a directory under arch/$ARCH/boot/dts as an include path
that has links outside of the subtree to find dt-bindings from under
include/dt-bindings. That's been working well, but new DT architectures
haven't been adding them by default.

Recently there's been a desire to share some of the DT material between
arm and arm64, which originally caused developers to create symlinks or
relative includes between the subtrees. This isn't ideal -- it breaks
if the DT files aren't stored in the exact same hierarchy as the kernel
tree, and generally it's just icky.

As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
once, and allow DTS files to reference dtsi (and dts) files in other
architectures that way.

Original approach was to create these links under each architecture,
but it lead to the problem of recursive symlinks.

As a remedy, move the include link directories out of the architecture
trees into a common location. At the same time, they can now share one
directory and one dt-bindings/ link as well.

6ab5901837 MIPS: qi_lb60: Probe RTC driver from DT and use it as power controller
Since we already have a devicetree node for the jz4740-rtc driver, we
don't have to probe it from platform code.

Besides, using the jz4740-rtc driver as the power controller for the
qi_lb60 platform allows us to remove the jz4740 platform power-off code,
since this is the only jz4740-based board upstream.

93032e31a5 MIPS: Malta: Fixup reboot
Commit 10b6ea0959 ("MIPS: Malta: Use syscon-reboot driver to reboot")
converted the Malta board to use the generic syscon-reboot driver to
handle reboots, but incorrectly used the value 0x4d rather than 0x42 as
the magic to write to the reboot register.

I also incorrectly believed that syscon/regmap would default to native
endianness, but this isn't the case. Force this by specifying with a
native-endian property in the devicetree.

3f5f0a4475 MIPS: generic: Convert SEAD-3 to a generic board
Convert the MIPS SEAD-3 board support to be a generic board, supported
by generic kernels.

Because the SEAD-3 boot protocol was defined long ago and we don't want
to force a switch to the UHI protocol, SEAD-3 is added as a legacy board
which is detected by reading the REVISION register. This may technically
not be a valid memory read & future work will include attempting to
handle that gracefully. In practice since SEAD-3 is the only legacy
board supported by the generic kernel so far the read will only happen
on SEAD-3 boards, and even once Malta is converted the same REVISION
register exists there too. Other boards such as Boston, Ci20 & Ci40 will
use the UHI boot protocol & thus not run any of the legacy board detect
functions.

eed0eabd12 MIPS: generic: Introduce generic DT-based board support
Introduce a "generic" platform, which aims to be board-agnostic by
making use of device trees passed by the boot protocol defined in the
MIPS UHI (Universal Hosting Interface) specification. Provision is made
for supporting boards which use a legacy boot protocol that can't be
changed, but adding support for such boards or any others is left to
followon patches.

Right now the built kernels expect to be loaded to 0x80100000, ie. in
kseg0. This is fine for the vast majority of MIPS platforms, but
nevertheless it would be good to remove this limitation in the future by
mapping the kernel via the TLB such that it can be loaded anywhere & map
itself appropriately.

Configuration is handled by dynamically generating configs using
scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc
makes use of it. This allows for variations upon the configuration, eg.
differing architecture revisions or subsets of driver support for
differing boards, to be handled without having a large number of
defconfig files.

cf2a5e0bb4 MIPS: Support generating Flattened Image Trees (.itb)
Add support for generating kernel images in the Flattened Image Tree
(.itb) format as supported by U-Boot. This format is essentially a
Flattened Device Tree binary containing images (kernels, DTBs, ramdisks)
and configurations which link those images together. The big advantages
of FIT images over the uImage format are:

  - We can include FDTs in the kernel image in a way that the bootloader
    can extract it & manipulate it before providing it to the kernel.
    Thus we can ship FDTs as part of the kernel giving us the advantages
    of being able to develop & maintain the DT within the kernel tree,
    but also have the benefits of the bootloader being able to
    manipulate the FDT. Example uses for this would be to inject the
    kernel command line into the chosen node, or to fill in the correct
    memory size.

  - We can include multiple configurations in a single kernel image.
    This means that a single FIT image can, given appropriate
    bootloaders, be booted on different boards with the bootloader
    selecting an appropriate configuration & providing the correct FDT
    to the kernel.

  - We can support a multitude of hashes over the data.

Since Malta is very configurable it's unknown whether a GIC will be

malta_dt_shim code is added in order to detect whether a GIC is present,
adjusting the DT to route interrupts correctly and nop out the GIC node
if no GIC is found.

Probe the UARTs on SEAD3 boards using device tree rather than platform
code, in order to reduce the amount of the latter. This requires that
CONFIG_SERIAL_OF_PLATFORM be enabled, so enable it in sead3_defconfig.
The SEAD3 DT shim code is extended to read bootloader environment
variables to determine the appropriate UART & mode for kernel console
output & set the stdout-path property of the chosen node accordingly.

In contrast to the old platform code, which appears to have only ever
set "console=ttyS0,38400n8r" with the code in console_config never
having an effect, this will honor the "yamontty" environment variable to
select between the 2 UARTs on the board and then check the "modetty0" or
"modetty1" variable as appropriate to determine the UART configuration.

b6d5e47e67 MIPS: SEAD3: Probe interrupt controllers using DT
Probe the CPU interrupt controller & optional Global Interrupt
Controller (GIC) using devicetree rather than platform code. Because the
bootloader on SEAD3 does not provide a device tree to the kernel & the
device tree is always built in, we patch out the GIC node during boot if
we detect that a GIC is not present in the system.

The appropriate IRQ domain is discovered by platform code setting up
device IRQ numbers temporarily. It will be removed by further patches
which move the devices towards being probed via device tree.

No behavioural change is intended by this patch.

The DT fragment will select the ohci-platform driver, since that can
handle the JZ4740 OHCI just fine. While I don't have a JZ4740-based
board with anything connected to the USB host controller, I did test
the generic OHCI driver successfully on a JZ4770-based board.

The device is disabled by default; boards that want to use it can
override the "status" property. The mass-production Qi LB60 boards
don't use the USB host controller.

766c580356 MIPS: tools: Add relocs tool
This tool is based on the x86/boot/tools/relocs tool.

It parses the relocations present in the vmlinux elf file, building a
table of relocations that will be necessary to run the kernel from an
address other than its link address. This table is inserted into the
vmlinux elf, in the .data.relocs section. The table is subsequently used
by the code in arch/mips/kernel/relocate.c (added later) to relocate the
kernel.

The tool, by default, also marks all relocation sections as 0 length.
This is due to objcopy currently being unable to handle copying the
relocations between 64 and 32 bit elf files as is done when building a
64 bit kernel.

3bdf1071ba MIPS: ath79: update devicetree clock support for AR9132
Current ath79 clock.c code does not read reference clock and
pll setup from devicetree. E.g. you can set any clock rate value
in board DTS but it will have no effect on the real clk calculation.

This patch fixes some AR9132 devicetree clock support defects:

  * clk initialization function ath79_clocks_init_dt_ng()
    is introduced; it actually gets pll block base register
    address and reference clock from devicetree;
  * pll register parsing code is moved to the separate
    ar724x_clk_init() function; this function
    can be called from platform code or from devicetree code.

Also mips_hpt_frequency value is set from dt, so the appropriate
clock parameter is added to the cpu@0 devicetree node.

The same approach can be used for adding AR9331 devicetree support.

The include/dt-bindings/clock/ath79-clk.h header file
is introduced so we can use symbolic identifiers for SoC clocks.

83fe838466 MIPS: dts: qca: ar9132: use short references for dt nodes
Here are some Sascha Hauer's arguments for using aliases in the dts
files:

 - using aliases reduces the number of indentations in dts files;

 - dts files become independent of the layout of the dtsi files
   (it becomes possible to introduce another bus {} hierarchy between
   a toplevel bus and the devices when you have to);

 - less chances for typos. if &i2c2 does not exist you get an error.
   If instead you duplicate the whole path in the dts file a typo
   in the path will just create another node.

2cdfec1bbb MIPS: dts: qca: ar9132_tl_wr1043nd_v1.dts: drop unused alias node
The TP-LINK TL-WR1043ND board has only one serial port,
so replacing the default of 0 with 0 does nothing useful.

Moreover, the correct name for aliases node is "aliases" not "alias".

An overview of the "aliases" node usage can be found
on the device tree usage page at devicetree.org [1].

Also please see chapter 3.3 ("Aliases node") of the ePAPR 1.1 [2].

842c1e2c4a MIPS: Octeon: Add DTS for EdgeRouter Lite
Add DTS for EdgeRouter Lite that is usable as is without any "pruning"
with APPENDED_DTB.

Compared to builtin generic DTB, we can avoid errors and delays from
probing non-existent I2C devices.

Add DTS for D-Link DSR-1000N that is usable as is without any "pruning"
with APPENDED_DTB. Split out the common parts from octeon_3xxx.dts
into octeon_3xxx.dtsi.

Compared to builtin generic DTB, we can specificy fixed links properly
and avoid probing non-existent I2C devices.

b3f0a250d6 MIPS: ath79: Add zboot debug serial support
Reuse the early printk code to support the serial in zboot. We copy
early_printk.c instead of referencing it because we need to build a
different object file for the normal kernel and zboot.
