The SPI NAND subsystem has seen the introduction of DTR operations (the
equivalent of DDR transfers), which involved quite a few preparation
patches for clarifying macro names.
In the raw NAND subsystem, the brcmnand driver has been "fixed" for old
legacy SoCs with an update of the ->exec_op() hook, there has been the

Enabling the compile test should not cause automatic enabling of all
drivers, but only allow to choose to compile them.

Add support for the AC5/AC5X SoC from Marvell. The NFC on this SoC only

Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

The root of the problem is that we are selecting symbols that have
dependencies. This can cause random configurations that can fail.
The cleanest solution is to avoid using select.
This driver uses interfaces from the OMAP_GPMC driver so we have to
depend on it instead.

We need to select MEMORY as well otherwise OMAP_GPMC will not be built.
For simplicity let's select MEMORY and OMAP_GPMC unconditionally as
this driver depends on OMAP_GPMC driver and uses symbols from there.

Add a BCMA shim to allow us to register the brcmnand driver using the
BCMA bus which provides indirect memory mapped access to SoC registers.
There are a number of registers that need to be byte swapped because
they are natively big endian, coming directly from the NAND chip, and
there is no bus interface unlike the iProc or STB platforms that
performs the byte swapping for us.

The Ericsson U300 platform was one of two ARM929 based SoC platforms for
mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP
into ST-Ericsson, the other one being the ST Nomadik.
The platform was not widely adopted in Linux based systems and was
replaced with the far superior ST-Ericsson U8500 in 2011, but Linus
Walleij kept maintaining the code for the whole time.
Linus continues to use the Nomadik machine, but decided to drop
u300 from the kernel as part of this year's spring cleaning.
Thanks for having maintained it all these years.

This driver supports Rockchip NFC (NAND Flash Controller) found on RK3308,
RK2928, RKPX30, RV1108 and other SOCs. The driver has been tested using
8-bit NAND interface on the ARM based RK3308 platform.
Support Rockchip SoCs and NFC versions:
- PX30 and RK3326(NFCv900).
ECC: 16/40/60/70 bits/1KB.
CLOCK: ahb and nfc.
- RK3308 and RV1108(NFCv800).
ECC: 16 bits/1KB.
CLOCK: ahb and nfc.
- RK3036 and RK3128(NFCv622).
ECC: 16/24/40/60 bits/1KB.
CLOCK: ahb and nfc.
- RK3066, RK3188 and RK2928(NFCv600).
ECC: 16/24/40/60 bits/1KB.
CLOCK: ahb.
Supported features:
- Read full page data by DMA.
- Support HW ECC(one step is 1KB).
- Support 2 - 32K page size.
- Support 8 CS(depend on SoCs)
Limitations:
- No support for the ecc step size is 512.
- Untested on some SoCs.
- No support for subpages.
- No support for the builtin randomizer.
- The original bad block mask is not supported. It is recommended to use
the BBT(bad block table).

Merge tag 'nand/for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux into mtd/next
Core changes:
* Drop useless 'depends on' in Kconfig
* Add an extra level in the Kconfig hierarchy
* Trivial spellings
* Dynamic allocation of the interface configurations
* Dropping the default ONFI timing mode
* Various cleanup (types, structures, naming, comments)
* Hide the chip->data_interface indirection
* Add the generic rb-gpios property
* Add the ->choose_interface_config() hook
* Introduce nand_choose_best_sdr_timings()
* Use default values for tPROG_max and tBERS_max

FMC2 EBI support has been added. Common resources (registers base
address and clock) can now be shared between the 2 drivers using
"st,stm32mp1-fmc2-nfc" compatible string. It means that the
common resources should now be found in the parent device when EBI
node is available.

Both OneNAND and raw NAND bits can't be compiled if MTD is disabled
because of the if/endif logic in drivers/mtd/Kconfig. There is no need
for an extra "depends on MTD" in their respective Kconfig files.

Add support for the hardware ECC BCH engine.
Please mind that this engine has an important limitation:
BCH implementation does not inform the user when an uncorrectable ECC
error occurs. To workaround this, we avoid using the hardware engine
in the read path and do the computation with the software BCH
implementation, which is faster than mixing hardware (for correction)
and software (for verification).

Add the Arasan NAND controller driver. This brings only NAND
controller support. The ECC engine being a bit subtle, hardware ECC
support will be added in a second time.
This work is based on contributions from Naga Sureshkumar Relli.

Currently CONFIG_MTD_NAND_CADENCE implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:
ld: drivers/mtd/nand/raw/cadence-nand-controller.o: in function `cadence_nand_dt_probe.cold.31':
drivers/mtd/nand/raw/cadence-nand-controller.c:2969: undefined reference to `devm_platform_ioremap_resource'
ld: drivers/mtd/nand/raw/cadence-nand-controller.c:2977: undefined reference to `devm_ioremap_resource'
Fix the build error by adding the unspecified dependency.
