means that polling using chip_good() always reaches a timeout condition
when erase or program failure bits are set. Let's fully delegate the task
of determining the error conditions to cfi_check_err_status() and make
chip_good() only look for the Device Ready/Busy condition.

the sequencer mode). By enabling this feature, we can't poll the status

until R/B# signal is high, and locks the CPU bus.
To avoid to lock the CPU bus, we poll FMC2 ISR register. This register

commit a3c4c2339f upstream.
Change calculating of position page containing BBM
If none of BBM flags are set then function nand_bbm_get_next_page
reports EINVAL. It causes that BBM is not read at all during scanning
factory bad blocks. The result is that the BBT table is build without
checking factory BBM at all. For Micron flash memories none of these
flags are set if page size is different than 2048 bytes.
Address this regression by:
- adding NAND_BBM_FIRSTPAGE chip flag without any condition. It solves
issue only for Micron devices.
- changing the nand_bbm_get_next_page_function. It will return 0
if no of BBM flag is set and page parameter is 0. After that modification
way of discovering factory bad blocks will work similar as in kernel
version 5.1.

commit 69c7f4618c 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

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.

The code change updated the NAND driver BCH ECC layout algorithm to
support large oob size NAND chips(oob > 1024 bytes) and proposed a new
way to set ECC layout.
Current implementation requires each chunk size larger than oob size so
the bad block marker (BBM) can be guaranteed located in data chunk. The
ECC layout always using the unbalanced layout(Ecc for both meta and
Data0 chunk), but for the NAND chips with oob larger than 1k, the driver
cannot support because BCH doesn’t support GF 15 for 2K chunk.
The change keeps the data chunk no larger than 1k and adjust the ECC
strength or ECC layout to locate the BBM in data chunk. General idea for
large oob NAND chips is
1.Try all ECC strength from the minimum value required by NAND spec to
the maximum one that works, any ECC makes the BBM locate in data chunk
can be chosen.
2.If none of them works, using separate ECC for meta, which will add one
extra ecc with the same ECC strength as other data chunks. This extra
ECC can guarantee BBM located in data chunk, of course, we need to check
if oob can afford it.
Previous code has two methods for ECC layout setting, the
legacy_set_geometry and set_geometry_by_ecc_info, the difference between
these two methods is, legacy_set_geometry set the chunk size larger chan
oob size and then set the maximum ECC strength that oob can afford.
While the set_geometry_by_ecc_info set chunk size and ECC strength
according to NAND spec. It has been proved that the first method cannot
provide safe ECC strength for some modern NAND chips, so in current
code,
1. Driver read NAND parameters first and then chose the proper ECC
layout setting method.
2. If the oob is large or NAND required data chunk larger than oob
size, chose set_geometry_for_large_oob, otherwise use
set_geometry_by_ecc_info
3. legacy_set_geometry only used for some NAND chips does not
contains necessary information. So this is only a backup plan, it is NOT
recommended to use these NAND chips.

Commit 7e534323c4 ("mtd: rawnand: Pass a nand_chip object to

read_buf function pointer. In the au1550nd driver we have 2
implementations of read_buf. The previously mentioned commit modified
the au_read_buf() implementation to match the function pointer, but not
au_read_buf16(). This results in a compiler warning for MIPS
db1xxx_defconfig builds:
drivers/mtd/nand/raw/au1550nd.c:443:57:
warning: pointer type mismatch in conditional expression
Fix this by updating the prototype of au_read_buf16() to take a struct
nand_chip pointer as its first argument, as is expected after commit
7e534323c4 ("mtd: rawnand: Pass a nand_chip object to chip->read_xxx()

Note that this shouldn't have caused any functional issues at runtime,
since the offset of the struct mtd_info within struct nand_chip is 0
making mtd_to_nand() effectively a type-cast.

Pull misc mount API conversions from Al Viro:
"Conversions to new API for shmem and friends and for mount_mtd()-using
filesystems.
As for the rest of the mount API conversions in -next, some of them
belong in the individual trees (e.g. binderfs one should definitely go
through android folks, after getting redone on top of their changes).
I'm going to drop those and send the rest (trivial ones + stuff ACKed
by maintainers) in a separate series - by that point they are
independent from each other.
Some stuff has already migrated into individual trees (NFS conversion,
for example, or FUSE stuff, etc.); those presumably will go through
the regular merges from corresponding trees."

The chip state is set to erasing by the function after getting chip.
So it should be to get chip as erasing mode at first.
But previously it was to get chip as writing mode then fix as erasing.

In sm_init_zone(), 'zone->lba_to_phys_table' is allocated through
kmalloc_array() and 'zone->free_sectors' is allocated in kfifo_alloc()
respectively. However, they are not deallocated in the following execution
if sm_read_sector() fails, leading to memory leaks. To fix this issue, free
them before returning -EIO.
