commit 49c64df880570034308e4a9a49c4bc95cf8cdb33 upstream.
The variable 'name' is released multiple times in the error path,
which may cause double free issues.
This problem is avoided by adding a goto label to release the memory
uniformly. And this change also makes the code a bit more cleaner.

commit 4da0ea71ea934af18db4c63396ba2af1a679ef02 upstream.
This function is only called from lpddr_probe(). We free "lpddr" both
here and in the caller, so it's a double free. The best place to free
"lpddr" is in lpddr_probe() so let's delete this one.

commit 5d3805af279c93ef49a64701f35254676d709622 upstream.
If "seen_pebs = init_seen(ubi);" fails then "seen_pebs" is an error pointer
and we try to kfree() it which results in an Oops.
This patch re-arranges the error handling so now it only frees things
which have been allocated successfully.

commit ef5aafb6e4e9942a28cd300bdcda21ce6cbaf045 upstream.
set_seen() sets the bit corresponding to the PEB number in the bitmap,
so when self_check_seen() wants to find PEBs that haven't been seen we
have to print the PEBs that have their bit cleared, not the ones which
have it set.

commit a719a75a7761e4139dd099330d9fe3589d844f9b upstream.
spi_nor_read() assigns the result of 'ssize_t spi_nor_read_data()'
to the 'int ret' variable, while 'ssize_t' is a 64-bit type and *int*
is a 32-bit type on the 64-bit machines. This silent truncation isn't
really valid, so fix up the variable's type.

commit 69c7f4618c16b4678f8a4949b6bb5ace259c0033 upstream.
Any write with either dd or flashcp to a device driven by the
spear_smi.c driver will pass through the spear_smi_cpy_toio()
function. This function will get called for chunks of up to 256 bytes.
If the amount of data is smaller, we may have a problem if the data
length is not 4-byte aligned. In this situation, the kernel panics
during the memcpy:
# dd if=/dev/urandom bs=1001 count=1 of=/dev/mtd6
spear_smi_cpy_toio [620] dest c9070000, src c7be8800, len 256
spear_smi_cpy_toio [620] dest c9070100, src c7be8900, len 256
spear_smi_cpy_toio [620] dest c9070200, src c7be8a00, len 256
spear_smi_cpy_toio [620] dest c9070300, src c7be8b00, len 233
Unhandled fault: external abort on non-linefetch (0x808) at 0xc90703e8
[...]
PC is at memcpy+0xcc/0x330
The above error occurs because the implementation of memcpy_toio()
tries to optimize the number of I/O by writing 4 bytes at a time as
much as possible, until there are less than 4 bytes left and then
switches to word or byte writes.
Unfortunately, the specification states about the Write Burst mode:
"the next AHB Write request should point to the next
incremented address and should have the same size (byte,
half-word or word)"
This means ARM architecture implementation of memcpy_toio() cannot
reliably be used blindly here. Workaround this situation by update the
write path to stick to byte access when the burst length is not
multiple of 4.

commit 37c673ade35c707d50583b5b25091ff8ebdeafd7 upstream.
As reported by the OpenWRT team, write requests sometimes fail on some
platforms.
Currently to check the state chip_ready() is used correctly as described by
the flash memory S29GL256P11TFI01 datasheet.
Also chip_good() is used to check if the write is succeeded and it was
implemented by the commit fb4a90bfcd6d8 ("[MTD] CFI-0002 - Improve error
checking").
But actually the write failure is caused on some platforms and also it can
be fixed by using chip_good() to check the state and retry instead.
Also it seems that it is caused after repeated about 1,000 times to retry
the write one word with the reset command.
By using chip_good() to check the state to be done it can be reduced the
retry with reset.
It is depended on the actual flash chip behavior so the root cause is
unknown.

commit 336d4b138be2dad372b67a2388e42805c48aaa38 upstream.
One main goal of the function mtk_nfc_update_ecc_stats is to check
whether sectors are all empty. If they are empty, set these sectors's
data buffer and OOB buffer as 0xff.
But now, the sector OOB buffer pointer is wrongly assigned. We always
do memset from sector 0.
To fix this issue, pass start sector number to make OOB buffer pointer
be properly assigned.

commit d5d27fd9826b59979b184ec288e4812abac0e988 upstream.
Disable BCH soft reset according to MX23 erratum #2847 ("BCH soft
reset may cause bus master lock up") for MX28 too. It has the same
problem.
Observed problem: once per 100,000+ MX28 reboots NAND read failed on
DMA timeout errors:
[ 1.770823] UBI: attaching mtd3 to ubi0
[ 2.768088] gpmi_nand: DMA timeout, last DMA :1
[ 3.958087] gpmi_nand: BCH timeout, last DMA :1
[ 4.156033] gpmi_nand: Error in ECC-based read: -110
[ 4.161136] UBI warning: ubi_io_read: error -110 while reading 64
bytes from PEB 0:0, read only 0 bytes, retry
[ 4.171283] step 1 error
[ 4.173846] gpmi_nand: Chip: 0, Error -1
Without BCH soft reset we successfully executed 1,000,000 MX28 reboots.
I have a quote from NXP regarding this problem, from July 18th 2016:
"As the i.MX23 and i.MX28 are of the same generation, they share many
characteristics. Unfortunately, also the erratas may be shared.
In case of the documented erratas and the workarounds, you can also
apply the workaround solution of one device on the other one. This have
been reported, but I’m afraid that there are not an estimated date for
updating the Errata documents.
Please accept our apologies for any inconveniences this may cause."

commit 2a9d92fb3a1282a4659f1bb6d5684018846537b7 upstream.
I ran into a link-time error with the atmel-quadspi driver on the
EBSA110 platform:

:(.text+0x1ee3c): undefined reference to `_memcpy_toio'
:(.text+0x1ee48): undefined reference to `_memcpy_fromio'
The problem is that _memcpy_toio/_memcpy_fromio are not available on
that platform, and we have to prevent building the driver there.
In case we want to backport this to older kernels: between linux-4.8
and linux-4.20, the Kconfig entry was in drivers/mtd/spi-nor/Kconfig
but had the same problem.

The device tree property fsl,legacy-bch-geometry was only evaluated
when nand-on-flash-bbt was also defined. This looks wrong.
In mainline (as of 4.12) fsl,legacy-bch-geometry doesn't exist,
its functionality seems to be taken over by the fsl,use-minimum-ecc
property and it is used independent of nand-on-flash-bbt.
The move of code gets also rid of the following compiler warning:

commit be2e1c9dcf76886a83fb1c433a316e26d4ca2550 upstream.
I noticed during the creation of another bugfix that the BCH_CONST_PARAMS
option that is set by DOCG3 breaks setting variable parameters for any
other users of the BCH library code.
The only other user we have today is the MTD_NAND software BCH
implementation (most flash controllers use hardware BCH these days
and are not affected). I considered removing BCH_CONST_PARAMS entirely
because of the inherent conflict, but according to the description in
lib/bch.c there is a significant performance benefit in keeping it.
To avoid the immediate problem of the conflict between MTD_NAND_BCH
and DOCG3, this only sets the constant parameters if MTD_NAND_BCH
is disabled, which should fix the problem for all cases that
are affected. This should also work for all stable kernels.
Note that there is only one machine that actually seems to use the
DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have
the driver disabled, but it almost certainly shows up if we wanted
to test random kernels on machines that use software BCH in MTD.

[ Upstream commit 6c6bc9ea84d0008024606bf5ba10519e20d851bf ]
The first checks in mtdchar_read() and mtdchar_write() attempt to limit
`count` such that `*ppos + count <= mtd->size`. However, they ignore the
possibility of `*ppos > mtd->size`, allowing the calculation of `count` to
wrap around. `mtdchar_lseek()` prevents seeking beyond mtd->size, but the
pread/pwrite syscalls bypass this.
I haven't found any codepath on which this actually causes dangerous
behavior, but it seems like a sensible change anyway.

commit 7233982ade15eeac05c6f351e8d347406e6bcd2f upstream.
Fix to return error code -ENOMEM from the kmem_cache_alloc() error
handling case instead of 0, as done elsewhere in this function.

FLEXSPI AHBCR register has one bit READADDROPT, which defined if start
address must be aligned when doing wordaddress access. This bit must be
set (no alignment limitation), otherwise controller may always try
to access from even address and got wrong data when AHB read data under
Octal DDR mode. Mounting UBIFS failed in this case since it read from
odd address.

This patch removes the WARN_ONCE() test in spi_nor_write().
This macro triggers the display of a warning message almost every time we
use a UBI file-system because a write operation is performed at offset 64,
which is in the middle of the SPI NOR memory page. This is a valid
operation for ubifs.
Hence this warning is pretty annoying and useless so we just remove it.
