A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity. This pull
request includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the memory
subsystem doesn't seem to have a fixed maintainer at the minute and this
seemed like the most sensible way to get that hardware supported.
- Quite a few cleanups and optimizations for the Altera, Qualcomm GENI,
sun6i and lantiq drivers.
- Several more GPIO descriptor conversions.
- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
R8A774e1.

Following process triggers a memleak caused by forgetting to release the
initial next anchor PEB (CONFIG_MTD_UBI_FASTMAP is disabled):
1. attach -> __erase_worker -> produce the initial next anchor PEB

Both w25q64 and s25fl064k nor flash support QUAD and DUAL read
command, hence update the same in flash_info table.
This is tested on Broadcom Stingray SoC (bcm958742t).
s25fl064k and w25q64 share the same JEDEC ID. The search alg will
return the first hit, so s25fl064k even for the winbond parts. We
should differentiate between these flashes, but it's not in the

After spi_nor_write_disable() return code checks were introduced in the
spi-nor front end intel-spi backend stopped to work because WRDI was never
supported and always failed.
Just pretend it was sucessful and ignore the command itself. HW sequencer
shall do the right thing automatically, while with SW sequencer we cannot
do it anyway, because the only tool we had was preopcode and it makes no
sense for WRDI.

When doing a "write" ioctl call, properly check that we have permissions
to do so before copying anything from userspace or anything else so we
can "fail fast". This includes also covering the MEMWRITE ioctl which
previously missed checking for this.

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

If the flash's quad mode is enabled, it'll remain in the quad mode when
it's removed. If we drive the flash next time in Standard/Dual SPI mode,
the QE bit is not cleared and the function of flash's WP# and RESET#/HOLD#
have been switched to IO2 and IO3 and are not restored.
Disable the Quad mode in spi_nor_restore(), then the flash's QE bit will
be cleared when removed. This will make sure the flash always enter the
Standard/Dual SPI mode when loaded.

Previous we didn't provide a way to disable the flash's quad mode.
Which means we cannot do some cleanup works when to remove or

The Micron MT35XU512ABA flash does not support the quad enable bit. But
instead of programming the Quad Enable Require field to 000b ("Device
does not have a QE bit"), it is programmed to 111b ("Reserved").
While this is technically incorrect, it is not reason enough to abort
BFPT parsing. Instead, continue BFPT parsing and let flashes set it in
their fixup hooks.

The header file linux/uio.h includes crypto/hash.h which pulls in
most of the Crypto API. Since linux/uio.h is used throughout the
kernel this means that every tiny bit of change to the Crypto API
causes the entire kernel to get rebuilt.
This patch fixes this by moving it into lib/iov_iter.c instead
where it is actually used.
This patch also fixes the ifdef to use CRYPTO_HASH instead of just
CRYPTO which does not guarantee the existence of ahash.
Unfortunately a number of drivers were relying on linux/uio.h to
provide access to linux/slab.h. This patch adds inclusions of
linux/slab.h as detected by build failures.
Also skbuff.h was relying on this to provide a declaration for
ahash_request. This patch adds a forward declaration instead.

Implement ECC correctable and uncorrectable error handling for EDU
reads. If ECC correctable bitflips are encountered on EDU transfer,
read page again using PIO. This is needed due to a NAND controller
limitation where corrected data is not transferred to the DMA buffer
on ECC error. This applies to ECC correctable errors that are reported
by the controller hardware based on set number of bitflips threshold in
the controller threshold register, bitflips below the threshold are
corrected silently and are not reported by the controller hardware.

BAM is DMA controller on QCOM ipq platforms, BAM mode on NAND driver
is set by writing BAM_MODE_EN bit on NAND_CTRL register.
NAND_CTRL is an operational register and in BAM mode operational
registers are read only.
So, before enabling BAM mode by writing the NAND_CTRL register, check
if BAM mode was already enabled by the bootloader, and enable BAM mode
only if it is not enabled already.
