add_mtd_device() has a comment suggesting that the caller should have
set dev.parent. This is required to have the parent device symlink show
up in sysfs, but not for proper operation of the mtd device itself.
Currently we have five drivers registering mtd devices during module
initialization, so they don't actually provide a parent device to link
to. That means we cannot WARN_ON() here, as it would trigger false
positives.
Make the comment a bit less firm in its assertion that dev.parent should
be set.

mtd: nand_bbt: set the smallest size of bbt table
When using nandsim to simulate a 128K block nand with `overridesize = 1',
the size of mtd device is too small (mtd_size = 4 * block_size) to get the
right length of bbt. Then when creating bbt, kzmalloc() will return
ZERO_SIZE_PTR. This causes a NULL pointer oops when scanning bbt.

The ECC encoder supports up to 32-bit correction by using 60 error

Limitations:
- HW ECC: Only 2K page with 64+ OOB.
- HW ECC: Only 24 and 32-bit error correction implemented.
Raw writes have been tested using the generic nand_write_page_raw
implementation. However, raw reads are currently not possible
because the controller need to know whether we are going to use
the ECC mode already at NAND_CMD_READ0 command time. At this point
we do not have the information whether it is a raw read or a

mtd: provide proper 32/64-bit compat_ioctl() support for BLKPG
After a bit of poking around wondering why my 32-bit user-space can't
seem to send a proper ioctl(BLKPG) to an MTD on my 64-bit kernel
(ARM64), I noticed that struct blkpg_ioctl_arg is actually pretty
unsuitable for use in the ioctl() ABI, due to its use of raw pointers,
and its lack of alignment/packing restrictions (32-bit arch'es tend to
pack the 4 fields into 4 32-bit words, whereas 64-bit arch'es would add
padding after the third int, and make this 6 32-bit words).
Anyway, this means BLKPG deserves some special compat_ioctl handling. Do
the conversion in a small shim for MTD.
block/compat_ioctl.c already has compat support for the block subsystem,
but it does so by a re-marshalling data to/from user-space (see
compat_blkpg_ioctl()). Personally, I think this approach is cleaner.
Tested only on MTD, with an ARM32 user space on an ARM64 kernel.

mtd: spi-nor: scale up timeout for full-chip erase
This patch fixes timeout issues seen on large NOR flash (e.g., 16MB
w25q128fw) when using ioctl(MEMERASE) with offset=0 and length=16M. The
input parameters matter because spi_nor_erase() uses a different code
path for full-chip erase, where we use the SPINOR_OP_CHIP_ERASE (0xc7)
opcode.
Fix: use a different timeout for full-chip erase than for other
commands.
While most operations can be expected to perform relatively similarly
across a variety of NOR flash types and sizes (and therefore might as
well use a similar timeout to keep things simple), full-chip erase is
unique, because the time it typically takes to complete:
(1) is much larger than most operations and
(2) scales with the size of the flash.
Let's base our timeout on the original comments stuck here -- that a 2MB
flash requires max 40s to erase.
Small survey of a few flash datasheets I have lying around:
Chip Size (MB) Max chip erase (seconds)
---- -------- ------------------------
w25q32fw 4 50
w25q64cv 8 30
w25q64fw 8 100
w25q128fw 16 200
s25fl128s 16 ~256
s25fl256s 32 ~512
From this data, it seems plenty sufficient to say we need to wait for
40 seconds for each 2MB of flash.
After this change, it might make some sense to decrease the timeout for
everything else, as even the most extreme operations (single block
erase?) shouldn't take more than a handful of seconds. But for safety,
let's leave it as-is. It's only an error case, after all, so we don't
exactly need to optimize it.

A read id operation followed by 0x00 reads the device ID while

As the READID function did not propagate the second id parameter but had
a hard-coded call for 0x90 0x00, reading the ONFI identifier was not
possible and thus chips werde not detected (tested with

mtd: cmdlinepart: allow small partitions
I'm not sure why we have a PAGE_SIZE restriction on this partition
parser.
If we really wanted the restriction, I would expect it to be a
restriction for *all* parsers, so we'd move it to the MTD core
At any rate, while small partitions may not be useful (they'll often be
smaller than the eraseblock size and therefore can only be used
read-only), they still have use as a read-only partition.
This restriction is especially annoying because it aborts the entire
MTD's cmdline parsing, leaving it unpartitioned.
So, let's kill the restriction and only check for zero-sized partitions,
which I expect we don't want to allow.
