Refer to commit a85a6c86c25b ("driver core: platform: Clarify that IRQ
0 is invalid"). Do not check 0 for platform_get_irq(), because
platform_get_irq() never return zero, and use the return error code of
platform_get_irq() instead of -ENODEV.

Subject: [PATCH 09/91] mtd: spi-nor: convert .n_sectors to .size

.n_sectors is rarely used. In fact it is only used in swp.c and to
calculate the flash size in the core. The use in swp.c might be
converted to use the (largest) flash erase size. For now, we just
locally calculate the sector size.

Simplify the flash_info database and set the size of the flash directly.
This also let us use the SZ_x macros.

Verified that there's no flash that specifies BP and sector size of zero
to make sure we avoid a division by zero in
spi_nor_get_min_prot_length_sr(). We'll protect from a possible division
by zero in a further patch by introducing a default value for
sector_size.

The INFO() macro always set the page_size to 256 bytes. Make that an
optional parameter. This default is a sane one for all older flashes,
newer ones will set the page size by its SFDP tables anyway.

First, fixups might want to replace the n_banks parameter, thus we need
it in the (writable) parameter struct. Secondly, this way we can have a
default in the core and just skip setting the n_banks in the flash_info
database. Most of the flashes doesn't have more than one bank.

Subject: [PATCH 13/91] mtd: spi-nor: push 4k SE handling into
 spi_nor_select_uniform_erase()

4k sector erase sizes are only a thing with uniform erase types. Push
the "we want 4k erase sizes" handling into spi_nor_select_uniform_erase().

One might wonder why the former sector_size isn't used anymore. It is
because we either search for the largest erase size or if selected
through kconfig, the 4k erase size. Now, why is that correct? For this,
we have to differentiate between (1) flashes with SFDP and (2) without
SFDP. For (1), we just set one (or two if SECT_4K is set) erase types
and wanted_size is exactly one of these.

For (2) things are a bit more complicated. For flashes which we don't
have in our flash_info database, the generic driver is used and
sector_size was already 0, which in turn selected the largest erase
size. For flashes which had SFDP and an entry in flash_info, sector_size
was always the largest sector and thus the largest erase type.

Subject: [PATCH 14/91] mtd: spi-nor: make sector_size optional

Most of the (old, non-SFDP) flashes use a sector size of 64k. Make that
a default value so it can be optional in the flash_info database.

As a preparation for conversion to the new database format, set the
sector size to zero if the default value is used. This way, the actual
change is happening with this patch ant not with a later conversion
patch.

Subject: [PATCH 15/91] mtd: spi-nor: drop .parse_sfdp

Drop the size parameter to indicate we need to do SFDP, we can do that
because it is guaranteed that the size will be set by SFDP and because
PARSE_SFDP forced the SFDP parsing it must be overwritten.

There is a (very tiny) chance that this might break block protection
support: we now rely on the SFDP reported size of the flash for the
BP calculation. OTOH, if the flash reports its size wrong, we are
in bigger trouble than just having the BP calculation wrong.

Subject: [PATCH 16/91] mtd: spi-nor: introduce (temporary) INFO0()

The id will be converted to an own structure. To differentiate between
flashes with and without IDs, introduce a temporary macro INFO0() and
convert all flashes with no ID to use it. The difference between INFO0()
and INFOx() is that the former, doesn't have a pointer to the id
structure. Something which isn't possible to do within the INFOx()
macro.
After the flash_info conversion, that macro will be removed along with
all the other INFOx() macros.

Subject: [PATCH 17/91] mtd: spi-nor: move the .id and .id_len into an own
 structure

Create a new structure to hold a flash ID and its length. The goal is to
have a new macro SNOR_ID() which can have a flexible id length. This way
we can get rid of all the individual INFOx() macros.

ops:
  .otp = SNOR_OTP(...),

There won't be any new entries, nor are the entries that much different
and the very odd page and sector sizes make the new format hard to read.
Therefore, convert the old S3AN_INFO() macro.

Subject: [PATCH 39/91] mtd: spi-nor: macronix: sort flash_info database

The flash ID is the new primary key into our database. Sort the entry by
it. Keep the most specific ones first, because there might be ID
collisions between shorter and longer ones.

Subject: [PATCH 41/91] mtd: spi-nor: spansion: sort flash_info database

The flash ID is the new primary key into our database. Sort the entry by
it. Keep the most specific ones first, because there might be ID
collisions between shorter and longer ones.

Subject: [PATCH 42/91] mtd: spi-nor: sst: sort flash_info database

The flash ID is the new primary key into our database. Sort the entry by
it. Keep the most specific ones first, because there might be ID
collisions between shorter and longer ones.

Subject: [PATCH 44/91] mtd: spi-nor: atmel: drop duplicate entry

The Atmel AT26DF321 and AT25DF321 have the same ID. Both were just
discovered by reading their IDs, that is, there is no probing by name.
Thus only the first one (the AT25DF321) in the list was ever probed.
Luckily, the AT25DF is also the newer series. Drop the AT26DF321.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct lpddr_private.

Subject: [PATCH 55/91] mtd: map_ram: prevent use of point and unpoint when
 NO_XIP is set

When the DT property no-unaligned-direct-access is set, map->phys is set
to NO_XIP. With this property set, the flash should not be exposed
directly to MTD users, since it cannot be mapped.

map_ram() exposes the flash direct access unconditionally which leads to
access errors (when the bus width does not match the RAM width).

Therefore do not set point and unpoint when NO_XIP is set.

 returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 63/91] mtd: powernv_flash: Convert to platform remove callback
 returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 72/91] mtd: maps: pxa2xx-flash: Convert to platform remove
 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 78/91] mtd: rawnand: arasan: Include ECC syndrome along with
 in-band data while checking for ECC failure

Following an ECC failure condition upon page reads, we shall distinguish
between a real ECC failure and an empty page. This is handled with a call
to nand_check_erased_ecc_chunk() which looks at the data and counts the
number of bits which are not 'ones'. If we get less zeros than the ECC
strength, we assume the page was erased and we are in the presence of
natural bitflips. Otherwise, if we are above, we assume some data was
written and the ECC engine could not recover it all, so we report an ECC
failure.

In order for this logic to be as close as the reality as we can (this is
already a simplified condition but we can hardly be more precise), we
should check all the data that is covered by the ECC step not only the
in-band data, so we should also include the ECC syndrome in the check.

Subject: [PATCH 79/91] mtd: rawnand: rockchip: Use struct_size()

Use struct_size() instead of hand writing it.
This is less verbose and more robust.

While at it, prepare for the coming implementation by GCC and Clang of the
__counted_by attribute. Flexible array members annotated with __counted_by
can have their accesses bounds-checked at run-time checking via
CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for
strcpy/memcpy-family functions).

Also remove a useless comment about the position of a flex-array in a
structure.

 __counted_by
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct
mtk_nfc_nand_chip.

The driver doesn't benefit from the advantages that
module_platform_driver_probe() allows (i.e. putting the probe function
in .init.text and the .remove function into .exit.text).
So use module_platform_driver() instead which allows to bind the driver
also after booting (or module loading) and unbinding via sysfs.

Subject: [PATCH 91/91] mtd: cfi_cmdset_0001: Byte swap OTP info

Currently the offset into the device when looking for OTP
bits can go outside of the address of the MTD NOR devices,
and if that memory isn't readable, bad things happen
on the IXP4xx (added prints that illustrate the problem before
the crash):

cfi_intelext_otp_walk walk OTP on chip 0 start at reg_prot_offset 0x00000100
ixp4xx_copy_from copy from 0x00000100 to 0xc880dd78
cfi_intelext_otp_walk walk OTP on chip 0 start at reg_prot_offset 0x12000000
ixp4xx_copy_from copy from 0x12000000 to 0xc880dd78
8<--- cut here ---
Unable to handle kernel paging request at virtual address db000000
[db000000] *pgd=00000000
(...)

This happens in this case because the IXP4xx is big endian and
the 32- and 16-bit fields in the struct cfi_intelext_otpinfo are not
properly byteswapped. Compare to how the code in read_pri_intelext()
byteswaps the fields in struct cfi_pri_intelext.

Adding a small byte swapping loop for the OTP in read_pri_intelext()
and the crash goes away.

The problem went unnoticed for many years until I enabled
CONFIG_MTD_OTP on the IXP4xx as well, triggering the bug.
