1d4c725453 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.

3ea3f0ac24 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.

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.

9b6bb07ead 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.

0554effe99 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.

74b7ad7683 mtd: spi-nor: xilinx: use SPI_NOR_ID() in S3AN_INFO()
In commit 5927318029 ("mtd: spi-nor: Create macros to define chip IDs
and geometries") SPI_NOR_ID() were introduced, but it did only update
the INFO() macro in core.h. Also use it in S3AN_INFO().

d9cd5c9a6f mtd: spi-nor: remove Fujitsu MB85RS1MT support
This part is not a flash but an EEPROM like FRAM. It is even has a DT
binding for the (correct) driver (at25), see
Documentation/devicetree/bindings/eeprom/at25.yaml. Just remove it.

022545e057 mtd: spi-nor: remove catalyst 'flashes'
CAT25xx are actually EEPROMs manufactured by Catalyst. The devices are
ancient (DS are from 1998), there are not in-tree users, nor are there
any device tree bindings. Remove it. The correct driver is the at25.

42aadec8c7 stat: remove no-longer-used helper macros
The choose_32_64() macros were added to deal with an odd inconsistency
between the 32-bit and 64-bit layout of 'struct stat' way back when in
commit a52dd971f9 ("vfs: de-crapify "cp_new_stat()" function").

Then a decade later Mikulas noticed that said inconsistency had been a
mistake in the early x86-64 port, and shouldn't have existed in the
first place.  So commit 932aba1e16 ("stat: fix inconsistency between
struct stat and struct compat_stat") removed the uses of the helpers.

But the helpers remained around, unused.

Get rid of them.
