59529bbe64 firmware: SDEI: Allow sdei initialization without ACPI_APEI_GHES
SDEI usually initialize with the ACPI table, but on platforms where
ACPI is not used, the SDEI feature can still be used to handle
specific firmware calls or other customized purposes. Therefore, it
is not necessary for ARM_SDE_INTERFACE to depend on ACPI_APEI_GHES.

In commit dc4e8c07e9 ("ACPI: APEI: explicit init of HEST and GHES
in acpi_init()"), to make APEI ready earlier, sdei_init was moved
into acpi_ghes_init instead of being a standalone initcall, adding
ACPI_APEI_GHES dependency to ARM_SDE_INTERFACE. This restricts the
flexibility and usability of SDEI.

This patch corrects the dependency in Kconfig and splits sdei_init()
into two separate functions: sdei_init() and acpi_sdei_init().
sdei_init() will be called by arch_initcall and will only initialize
the platform driver, while acpi_sdei_init() will initialize the
device from acpi_ghes_init() when ACPI is ready. This allows the
initialization of SDEI without ACPI_APEI_GHES enabled.

Fixes: dc4e8c07e9 ("ACPI: APEI: explicit init of HEST and GHES in apci_init()")

firmware: turris-mox-rwtm: Add support for ECDSA signatures with HW private key
Add support for digital message signing with the private key stored in
the rWTM secure coprocessor. Turris Mox devices have an ECDSA private
key generated and burned into rWTM eFuses when manufactured. This
private key is not readable from the rWTM, but rWTM firmware allows for
signing messages with it and retrieving the public key.

This is exposed to userspace via the keyctl API.

User can find the key by either looking at /proc/keys or listing the
keyring:

  $ cat /proc/keys
  0240b221 ... keyring   .turris-signing-keys: 1
  34ff9ac9 ... turris-si Turris MOX SN 0000000D30000005 rWTM ECDSA ke...

  $ keyctl rlist %:.turris-signing-keys
  889166537

To get the public key:

  $ keyctl read 889166537
  67 bytes of data in key:
  0201a05c 1a79242b 13f2fc02 b48ffdbb 6ee8d5ba 812d6784 5f04f302 c0894d3e

  $ dd if=/dev/urandom of=msg_to_sign bs=64 count=1
  $ keyctl pkey_sign 889166537 0 msg_to_sign >signature

e4b3cbd840 firmware: thead: Add AON firmware protocol driver
The T-Head TH1520 SoC uses an E902 co-processor running Always-On (AON)
firmware to manage power, clock, and other system resources [1]. This
patch introduces a driver implementing the AON firmware protocol,
allowing the Linux kernel to communicate with the firmware via mailbox
channels.  Through an RPC-based interface, the kernel can initiate power
state transitions, update resource configurations, and perform other
AON-related tasks.

Alive Clock and Power Manager (ACPM) Message Protocol is defined for
the purpose of communication between the ACPM firmware and masters
(AP, AOC, ...). ACPM firmware operates on the Active Power Management
(APM) module that handles overall power activities.

ACPM and masters regard each other as independent hardware component and
communicate with each other using mailbox messages and shared memory.

This protocol driver provides the interface for all the client drivers
making use of the features offered by the APM. Add ACPM protocol support.

75fa9b7e37 video: Add helpers for decoding screen_info
The plain values as stored in struct screen_info need to be decoded
before being used. Add helpers that decode the type of video output
and the framebuffer I/O aperture.

Old or non-x86 systems may not set the type of video directly, but
only indicate the presence by storing 0x01 in orig_video_isVGA. The
decoding logic in screen_info_video_type() takes this into account.
It then follows similar code in vgacon's vgacon_startup() to detect
the video type from the given values.

A call to screen_info_resources() returns all known resources of the
given screen_info. The resources' values have been taken from existing
code in vgacon and vga16fb. These drivers can later be converted to
use the new interfaces.

v2:
	* return ssize_t from screen_info_resources()
	* don't call __screen_info_has_lfb() unnecessarily

ec5b0f1193 firmware: microchip: add PolarFire SoC Auto Update support
Add support for Auto Update reprogramming of the FPGA fabric on
PolarFire SoC, using the fw_upload mechanism a la the
intel-m10-bmc-sec-update driver.

This driver only writes the image to the spi flash & performs
validation on it, as the entire FPGA becomes unusable during the actual
reprogramming of a bitstream. To initiate the reprogramming itself, a
device reset is required. The SBI SRST extension's "cold reboot" can
trigger such a device reset, provided corresponding support has been
enabled in the HSS (Hart Software Services), the provider of SBI runtime
services on PolarFire SoC.

While this is a driver responsible for the reprogramming of an FPGA,
there is no dynamic discovery of devices involved, as runtime
reconfiguration is not possible due to the device reset requirements.
Therefore FPGA manager subsystem is not used by this driver and the FPGA
subsystem maintainers were unwilling to accept it there.

759e7a2b62 firmware: Add support for Qualcomm UEFI Secure Application
On platforms using the Qualcomm UEFI Secure Application (uefisecapp),
EFI variables cannot be accessed via the standard interface in EFI
runtime mode. The respective functions return EFI_UNSUPPORTED. On these
platforms, we instead need to talk to uefisecapp. This commit provides
support for this and registers the respective efivars operations to
access EFI variables from the kernel.

Communication with uefisecapp follows the Qualcomm QSEECOM / Secure OS
conventions via the respective SCM call interface. This is also the
reason why variable access works normally while boot services are
active. During this time, said SCM interface is managed by the boot
services. When calling ExitBootServices(), the ownership is transferred
to the kernel. Therefore, UEFI must not use that interface itself (as
multiple parties accessing this interface at the same time may lead to
complications) and cannot access variables for us.

00b1248606 firmware: qcom_scm: Add support for Qualcomm Secure Execution Environment SCM interface
Add support for SCM calls to Secure OS and the Secure Execution
Environment (SEE) residing in the TrustZone (TZ) via the QSEECOM
interface. This allows communication with Secure/TZ applications, for
example 'uefisecapp' managing access to UEFI variables.

For better separation, make qcom_scm spin up a dedicated child
(platform) device in case QSEECOM support has been detected. The
corresponding driver for this device is then responsible for managing
any QSEECOM clients. Specifically, this driver attempts to automatically
detect known and supported applications, creating a client (auxiliary)
device for each one. The respective client/auxiliary driver is then
responsible for managing and communicating with the application.

While this patch introduces only a very basic interface without the more
advanced features (such as re-entrant and blocking SCM calls and
listeners/callbacks), this is enough to talk to the aforementioned
'uefisecapp'.

cf8e865810 arch: Remove Itanium (IA-64) architecture
The Itanium architecture is obsolete, and an informal survey [0] reveals
that any residual use of Itanium hardware in production is mostly HP-UX
or OpenVMS based. The use of Linux on Itanium appears to be limited to
enthusiasts that occasionally boot a fresh Linux kernel to see whether
things are still working as intended, and perhaps to churn out some
distro packages that are rarely used in practice.

None of the original companies behind Itanium still produce or support
any hardware or software for the architecture, and it is listed as
'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers
that contributed on behalf of those companies (nor anyone else, for that
matter) have been willing to support or maintain the architecture
upstream or even be responsible for applying the odd fix. The Intel
firmware team removed all IA-64 support from the Tianocore/EDK2
reference implementation of EFI in 2018. (Itanium is the original
architecture for which EFI was developed, and the way Linux supports it
deviates significantly from other architectures.) Some distros, such as
Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have
dropped support years ago.

While the argument is being made [1] that there is a 'for the common
good' angle to being able to build and run existing projects such as the
Grid Community Toolkit [2] on Itanium for interoperability testing, the
fact remains that none of those projects are known to be deployed on
Linux/ia64, and very few people actually have access to such a system in
the first place. Even if there were ways imaginable in which Linux/ia64
could be put to good use today, what matters is whether anyone is
actually doing that, and this does not appear to be the case.

There are no emulators widely available, and so boot testing Itanium is
generally infeasible for ordinary contributors. GCC still supports IA-64
but its compile farm [3] no longer has any IA-64 machines. GLIBC would
like to get rid of IA-64 [4] too because it would permit some overdue
code cleanups. In summary, the benefits to the ecosystem of having IA-64
be part of it are mostly theoretical, whereas the maintenance overhead
of keeping it supported is real.

So let's rip off the band aid, and remove the IA-64 arch code entirely.
This follows the timeline proposed by the Debian/ia64 maintainer [5],
which removes support in a controlled manner, leaving IA-64 in a known
good state in the most recent LTS release. Other projects will follow
once the kernel support is removed.

8b766b0f8e sysfb: Enable boot time VESA graphic mode selection
Since switch to simplefb/simpledrm VESA graphic mode selection with vga=
kernel parameter is no longer available with legacy BIOS.

The x86 realmode boot code enables the VESA graphic modes when option
FB_BOOT_VESA_SUPPORT is enabled.

This option is selected by vesafb but not simplefb/simpledrm.

To enable use of VESA modes with simplefb in legacy BIOS boot mode drop
dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix. Select
the option from sysfb rather than the drivers that depend on it.

The BOOT_VESA_SUPPORT is not specific to framebuffer but rather to x86
platform, move it from fbdev to x86 Kconfig.

dc4e8c07e9 ACPI: APEI: explicit init of HEST and GHES in apci_init()
From commit e147133a42 ("ACPI / APEI: Make hest.c manage the estatus
memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage
the estatus memory pool. On the other hand, ghes_init() relies on
sdei_init() to detect the SDEI version and (un)register events. The
dependencies are as follows:

    ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init()
    ghes_init() => sdei_init()

HEST is not PCI-specific and initcall ordering is implicit and not
well-defined within a level.

Based on above, remove acpi_hest_init() from acpi_pci_root_init() and
convert ghes_init() and sdei_init() from initcalls to explicit calls in the
following order:

    acpi_hest_init()
    ghes_init()
        sdei_init()

424953cf3c qcom_scm: hide Kconfig symbol
Now that SCM can be a loadable module, we have to add another
dependency to avoid link failures when ipa or adreno-gpu are
built-in:

aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe':
ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available'

ld.lld: error: undefined symbol: qcom_scm_is_available
>>> referenced by adreno_gpu.c
>>>               gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a

This can happen when CONFIG_ARCH_QCOM is disabled and we don't select
QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd
use a similar dependency here to what we have for QCOM_RPROC_COMMON,
but that causes dependency loops from other things selecting QCOM_SCM.

This appears to be an endless problem, so try something different this
time:

 - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on'
   but that is simply selected by all of its users

 - All the stubs in include/linux/qcom_scm.h can go away

 - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to
   allow compile-testing QCOM_SCM on all architectures.

 - To avoid a circular dependency chain involving RESET_CONTROLLER
   and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement.
   According to my testing this still builds fine, and the QCOM
   platform selects this symbol already.

5c785014b6 Qualcomm driver updates for v5.15
This fixes the "shared memory state machine" (SMSM) interrupt logic to
 avoid missing transitions happening while the interrupts are masked.
 
 SM6115 support is added to smd-rpm and rpmpd.
 
 The Qualcomm SCM firmware driver is once again made possible to compile
 and load as a kernel module.
 
 An out-of-bounds error related to the cooling devices of the AOSS driver
 is corrected. The binding is converted to YAML and a generic compatible
 is introduced to reduce the driver churn.
 
 The GENI wrapper gains a helper function used in I2C and SPI for
 switching the serial engine hardware to use the wrapper's DMA-engine.
 
 Lastly it contains a number of cleanups and smaller fixes for rpmhpd,
 socinfo, CPR, mdt_loader and the GENI DT binding.

Merge tag 'qcom-drivers-for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers

Qualcomm driver updates for v5.15

This fixes the "shared memory state machine" (SMSM) interrupt logic to
avoid missing transitions happening while the interrupts are masked.

SM6115 support is added to smd-rpm and rpmpd.

The Qualcomm SCM firmware driver is once again made possible to compile
and load as a kernel module.

An out-of-bounds error related to the cooling devices of the AOSS driver
is corrected. The binding is converted to YAML and a generic compatible
is introduced to reduce the driver churn.

The GENI wrapper gains a helper function used in I2C and SPI for
switching the serial engine hardware to use the wrapper's DMA-engine.

Lastly it contains a number of cleanups and smaller fixes for rpmhpd,
socinfo, CPR, mdt_loader and the GENI DT binding.

71260b9a70 drivers/firmware: fix SYSFB depends to prevent build failures
The Generic System Framebuffers support is built when the COMPILE_TEST
option is enabled. But this wrongly assumes that all the architectures
declare a struct screen_info.

This is true for most architectures, but at least the following do not:
arc, m68k, microblaze, openrisc, parisc and s390.

By attempting to make this compile testeable on all architectures, it
leads to linking errors as reported by the kernel test robot for parisc:

  All errors (new ones prefixed by >>):

     hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init':
     (.init.text+0x24): undefined reference to `screen_info'
  >> hppa-linux-ld: (.init.text+0x28): undefined reference to `screen_info'

To prevent these errors only allow sysfb to be built on systems that are
going to need it, which are x86 BIOS and EFI.

The EFI Kconfig symbol is used instead of (ARM || ARM64 || RISC) because
some of these architectures only declare a struct screen_info if EFI is
enabled. And also, because the SYSFB code is only used for EFI on these
architectures. For !EFI the "simple-framebuffer" device is registered by
OF when parsing the Device Tree Blob (if a DT node for this was defined).

8633ef82f1 drivers/firmware: consolidate EFI framebuffer setup for all arches
The register_gop_device() function registers an "efi-framebuffer" platform
device to match against the efifb driver, to have an early framebuffer for
EFI platforms.

But there is already support to do exactly the same by the Generic System
Framebuffers (sysfb) driver. This used to be only for X86 but it has been
moved to drivers/firmware and could be reused by other architectures.

Also, besides supporting registering an "efi-framebuffer", this driver can
register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers
on non-X86 EFI platforms. For example, on aarch64 these drivers can only
be used with DT and doesn't have code to register a "simple-frambuffer"
platform device when booting with EFI.

For these reasons, let's remove the register_gop_device() duplicated code
and instead move the platform specific logic that's there to sysfb driver.

d391c58271 drivers/firmware: move x86 Generic System Framebuffers support
The x86 architecture has generic support to register a system framebuffer
platform device. It either registers a "simple-framebuffer" if the config
option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device.

But the code is generic enough to be reused by other architectures and can
be moved out of the arch/x86 directory.

This will allow to also support the simple{fb,drm} drivers on non-x86 EFI
platforms, such as aarch64 where these drivers are only supported with DT.

b42000e4b8 firmware: qcom_scm: Allow qcom_scm driver to be loadable as a permenent module
Allow the qcom_scm driver to be loadable as a permenent module.

This still uses the "depends on QCOM_SCM || !QCOM_SCM" bit to
ensure that drivers that call into the qcom_scm driver are
also built as modules. While not ideal in some cases its the
only safe way I can find to avoid build errors without having
those drivers select QCOM_SCM and have to force it on (as
QCOM_SCM=n can be valid for those drivers).

Reviving this now that Saravana's fw_devlink defaults to on,
which should avoid loading troubles seen before.

The Arm FF for Armv8-A specification has concept of endpoints or
partitions. In the Normal world, a partition could be a VM when
the Virtualization extension is enabled or the kernel itself.

In order to handle multiple partitions, we can create a FFA device for
each such partition on a dedicated FFA bus. Similarly, different drivers
requiring FFA transport can be registered on the same bus. We can match
the device and drivers using UUID. This is mostly for the in-kernel
users with FFA drivers.

Merge tag 'arm-drivers-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "Updates for SoC specific drivers include a few subsystems that have
  their own maintainers but send them through the soc tree:

  TEE/OP-TEE:
   - Add tracepoints around calls to secure world

  Memory controller drivers:
   - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
   - Add debug statistics to Tegra20 memory controller
   - Update Tegra bindings and convert to dtschema

  ARM SCMI Firmware:
   - Support for modular SCMI protocols and vendor specific extensions
   - New SCMI IIO driver
   - Per-cpu DVFS

  The other driver changes are all from the platform maintainers
  directly and reflect the drivers that don't fit into any other
  subsystem as well as treewide changes for a particular platform.

  SoCFPGA:
   - Various cleanups contributed by Krzysztof Kozlowski

  Mediatek:
   - add MT8183 support to mutex driver
   - MMSYS: use per SoC array to describe the possible routing
   - add MMSYS support for MT8183 and MT8167
   - add support for PMIC wrapper with integrated arbiter
   - add support for MT8192/MT6873

  Tegra:
   - Bug fixes to PMC and clock drivers

  NXP/i.MX:
   - Update SCU power domain driver to keep console domain power on.
   - Add missing ADC1 power domain to SCU power domain driver.
   - Update comments for single global power domain in SCU power domain
     driver.
   - Add i.MX51/i.MX53 unique id support to i.MX SoC driver.

  NXP/FSL SoC driver updates for v5.13
   - Add ACPI support for RCPM driver
   - Use generic io{read,write} for QE drivers after performance
     optimized for PowerPC
   - Fix QBMAN probe to cleanup HW states correctly for kexec
   - Various cleanup and style fix for QBMAN/QE/GUTS drivers

  OMAP:
   - Preparation to use devicetree for genpd
   - ti-sysc needs iorange check improved when the interconnect target
     module has no control registers listed
   - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to
     avoid issues with missing resources and unnecessary deferred probe
   - ti-sysc debug option can now detect more devices
   - ti-sysc now warns if an old incomplete devicetree data is found as
     we now rely on it being complete for am3 and 4
   - soc init code needs to check for prcm and prm nodes for omap4/5 and
     dra7
   - omap-prm driver needs to enable autoidle retention support for
     omap4
   - omap5 clocks are missing gpmc and ocmc clock registers
   - pci-dra7xx now needs to use builtin_platform_driver instead of
     using builtin_platform_driver_probe for deferred probe to work

  Raspberry Pi:
   - Fix-up all RPi firmware drivers so as for unbind to happen in an
     orderly fashion
   - Support for RPi's PoE hat PWM bus

  Qualcomm
   - Improved detection for SCM calling conventions
   - Support for OEM specific wifi firmware path
   - Added drivers for SC7280/SM8350: RPMH, LLCC< AOSS QMP"

2954a6f12f firmware: qcom-scm: Fix QCOM_SCM configuration
When CONFIG_QCOM_SCM is y and CONFIG_HAVE_ARM_SMCCC
is not set, compiling errors are encountered as follows:

drivers/firmware/qcom_scm-smc.o: In function `__scm_smc_do_quirk':
qcom_scm-smc.c:(.text+0x36): undefined reference to `__arm_smccc_smc'
drivers/firmware/qcom_scm-legacy.o: In function `scm_legacy_call':
qcom_scm-legacy.c:(.text+0xe2): undefined reference to `__arm_smccc_smc'
drivers/firmware/qcom_scm-legacy.o: In function `scm_legacy_call_atomic':
qcom_scm-legacy.c:(.text+0x1f0): undefined reference to `__arm_smccc_smc'

Note that __arm_smccc_smc is defined when HAVE_ARM_SMCCC is y.
So add dependency on HAVE_ARM_SMCCC in QCOM_SCM configuration.

4a9a1a5602 arm64: socfpga: merge Agilex and N5X into ARCH_INTEL_SOCFPGA
Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and
SoC-part.  Up to a point that N5X uses the same DTSI as Agilex.  From
the Linux kernel point of view these are flavors of the same
architecture so there is no need for three top-level arm64
architectures.  Simplify this by merging all three architectures into
ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries.

The side effect is that the INTEL_STRATIX10_SERVICE will now be
available for both 32-bit and 64-bit Intel SoCFPGA, even though it is
used only for 64-bit.
