[PATCH v2 00/41] mtd: spi-nor: clean the flash_info database up

[PATCH v2 00/41] mtd: spi-nor: clean the flash_info database up

[Michael Walle]

The goal is to have slim entries for *new* entries and to have a
flexible macro to specify the flash ID and get rid of the former
INFOx() macros with the hardcoded ID length.

Here is are some examples how an entry of flash_info will look like
after the conversion:
  {
    .id = SNOR_ID(0xef, 0x80, 0x20),
    .name = "w25q512nwm",
    .otp = SNOR_OTP(256, 3, 0x1000, 0x1000),
  }

  {
    .id = SNOR_ID(0x01, 0x02, 0x19, 0x4d, 0x00, 0x80),
    .name = "s25fl256s0",
    .size = SZ_32M,
    .sector_size = SZ_256K,
    .no_sfdp_flags = SPI_NOR_SKIP_SFDP | SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ,
    .mfr_flags = USE_CLSR,
  }

Please note that the second entry might even be slimmed down if the
flash supports SFDP, which is very likely. But apart from one
exception, this patchset shouldn't change any information in the
flash_info database.

The exception is the removal of very old SPI EEPROMs and a Fujitsu MRAM.
Both should use the at25 EEPROM driver. The latter even has device tree
bindings for the at25 driver.

To make the entries as slim as possible, we introduce sane default
values so the actual flash_info entries, doesn't need to specify them.
This mostly applies to old non-SFDP flashes anyway.

Patches 01-02 remove the old catalyst EEPROMs and the Fujitsu MRAM.

Patches 03-16 are preparation patches to either convert properties
(like .n_sectors) or to make properties optional. These patches will
also modify the old INFOx() macros. This is important because with this
we can actually make sure, the conversion doesn't have any unwanted
changes. We can compare the .rodata segment before and after the
conversion to make sure, there are no mistakes in the patches, because
they are impossible to review.

To make sure there are no changes you can compare the output of
  objdump -j.rodata -s drivers/mtd/spi-nor/built-in.a

(or individual objects like drivers/mtd/spi-nor/winbond.o) before and
after the conversion, that is before patch 17 and after patch 30.

FWIW, before the conversion it was impossible to use coccinelle, eg.
"spatch --parse-c winbond.c" flagged almost all lines in the flash_info
structure as bad.

Now after the conversion is completed, patches 31-39 sort the
entries by their IDs.

Patch 40 removes a duplicate entry in atmel which surfaced during the
sorting.

Patch 41 then finally removes the old INFOx() macros.

[PATCH v2 01/41] mtd: spi-nor: remove catalyst 'flashes'

[Michael Walle]

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.

[PATCH v2 02/41] mtd: spi-nor: remove Fujitsu MB85RS1MT support

[Michael Walle]

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.

[PATCH v2 02/41] mtd: spi-nor: remove Fujitsu MB85RS1MT support

[Michael Walle]

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.

[PATCH v2 05/41] mtd: spi-nor: convert .n_sectors to .size

[Michael Walle]

.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.

[PATCH v2 06/41] mtd: spi-nor: default page_size to 256 bytes

[Michael Walle]

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.

[PATCH v2 07/41] mtd: spi-nor: store .n_banks in struct spi_nor_flash_parameter

[Michael Walle]

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.

[PATCH v2 09/41] mtd: spi-nor: push 4k SE handling into spi_nor_select_uniform_erase()

[Michael Walle]

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.

[PATCH v2 11/41] mtd: spi-nor: drop .parse_sfdp

[Michael Walle]

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.

[PATCH v2 11/41] mtd: spi-nor: drop .parse_sfdp

[Michael Walle]

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.

Signed-off-by: Michael Walle <mwalle@kernel.org>

[PATCH v2 12/41] mtd: spi-nor: introduce (temporary) INFO0()

[Michael Walle]

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. After the flash_info
conversion, that macro will be removed along with all the other INFOx()
macros.

[PATCH v2 13/41] mtd: spi-nor: move the .id and .id_len into an own structure

[Michael Walle]

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.

[PATCH v2 13/41] mtd: spi-nor: move the .id and .id_len into an own structure

[Michael Walle]

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.

[PATCH v2 14/41] mtd: spi-nor: rename .otp_org to .otp and make it a pointer

[Michael Walle]

Move the OTP ops out of the flash_info structure. Besides of saving some
space, there will be a new macro SNOR_OTP() which can be used to set the
ops:
  .otp = SNOR_OTP(...),

specify flashes in our database: SNOR_ID() and SNOR_OTP(). An flash_info
entry might now look like:

        .otp = SNOR_OTP(256, 3, 0x1000, 0x1000),

[PATCH v2 16/41] mtd: spi-nor: remove or move flash_info comments

[Michael Walle]

Most of the comments are a relict of the past when the flash_info was
just one table. Most of them are useless. Remove them.

[PATCH v2 29/41] mtd: spi-nor: xilinx: use new macros in S3AN_INFO()

[Michael Walle]

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.

Signed-off-by: Michael Walle <mwalle@kernel.org>
---
This collides with the atmel flashes and there seems to be a typo in the
IDs. All this makes me wonder wether we shouldn't deprecate the support
for this (FPGA configuration) flash.

[PATCH v2 29/41] mtd: spi-nor: xilinx: use new macros in S3AN_INFO()

[Michael Walle]

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.

This collides with the atmel flashes and there seems to be a typo in the
IDs. All this makes me wonder wether we shouldn't deprecate the support
for this (FPGA configuration) flash.

[PATCH v2 32/41] mtd: spi-nor: eon: sort flash_info database

[Michael Walle]

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.

[PATCH v2 35/41] mtd: spi-nor: macronix: sort flash_info database

[Michael Walle]

The flash ID is the new primary key into our database. Sort the entry by

[PATCH v2 36/41] mtd: spi-nor: micron-st: sort flash_info database

[Michael Walle]

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.

[PATCH v2 37/41] mtd: spi-nor: spansion: sort flash_info database

[Michael Walle]

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.

[PATCH v2 37/41] mtd: spi-nor: spansion: sort flash_info database

[Michael Walle]

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.

[PATCH v2 38/41] mtd: spi-nor: sst: sort flash_info database

[Michael Walle]

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.

[PATCH v2 39/41] mtd: spi-nor: winbond: sort flash_info entries

[Michael Walle]

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.

[PATCH v2 40/41] mtd: spi-nor: atmel: drop duplicate entry

[Michael Walle]

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 in the list was ever probed. The AT25DF is the
newer series. Drop the older one.

I noticed that we need this fix in the core. I'll have to think whether
we need to introduce nor->addr_mode_nbytes as well. I let this for after
I finish reviewing your series.

would be good to check the sanity of info->size to not be null and to be

Have a look at the later patches, info->size can be zero, indicating
that we need to parse SFDP for this flash.

I could validate that the size is a multiple of sector_size, but
that one might also be zero. Of course you could solve this by
additional logic. But I treated that one as a misconfiguration
of the flash_info entry. It's nothing which can happen during
runtime. Anyway, I have no strong opinion on the "is multiple
of sector_size" check (for now, maybe there's something I didn't
thought of now).

Please note that this is not the info->size, params->size cannot
be zero. If info->size was zero, we have to parse SFDP which hopefully
will give us a sane size.

And regarding the sector_size, which could be zero here. I want to
replace that logic, so we don't rely on the flash_info sector size.
 From a later patch:

         /*

Please note that this is not the info->size, params->size cannot
be zero. If info->size was zero, we have to parse SFDP which hopefully
will give us a sane size.

And regarding the sector_size, which could be zero here. I want to
replace that logic, so we don't rely on the flash_info sector size.
 From a later patch:

         /*
          * sector_size will eventually be replaced with the max erase 
size of
          * the flash. For now, we need to have that ugly default.

We'd first have to get rid of the Xilinx S3AN and the everspin stuff.
They are still using a different page size. That being said, that's
on my todo list.

one difference is that the is enabled check may now be evaluated for

one difference is that the is enabled check may now be evaluated for
each erase type, but looks cleaner and I can live with that as this is
set at probe time anyway.

We might get in trouble here if SFDP advertises a wrong flash size. And
this is because in BP, instead of relying on the info->sector_size, we
now compute locally the sector size based on the size advertised by
SFDP. And if the SFDP flash size is wrong, we'll break BP for this
flash. I'm ok taking this risk, but please update the commit message and
inform readers about what they may hit, and what would be the fix. With
that feel free to add:

We might get in trouble here if SFDP advertises a wrong flash size. And
this is because in BP, instead of relying on the info->sector_size, we
now compute locally the sector size based on the size advertised by
SFDP. And if the SFDP flash size is wrong, we'll break BP for this
flash. I'm ok taking this risk, but please update the commit message and
inform readers about what they may hit, and what would be the fix. With
that feel free to add:

this is a leftover that should be squashed in a previous commit.

I'm fine with the overal idea, but please fix the comment about the 3
bytes of jedec id.

this is a leftover that should be squashed in a previous commit.

I'm fine with the overal idea, but please fix the comment about the 3
bytes of jedec id.

Because that is also a preparation for the large conversion, where the
default value of 64k is dropped. And to be able to verify (because you
can't really review these conversion patches) the ro segments are the
same, this patch already set it to zero if the INFO entry has the
default size.

I'll amend the commit message.

I'd say if the SFDP advertises a wrong flash size we are in larger

The INFOn() macros will have a pointer to the SNOR_ID() whereas INFO0()
doesn't have a pointer. Before, it didn't really matter because we
tested for the id_len, but now we'll test the pointer (see next patch).

I just moved the description from flash_info :p

As far as I know, this isn't really specified at all, is it? I couldn't
even find that the "read jedec id" command 9F is specified anywhere. Do
you know more?

Also the first three bytes is also wrong. It might be more or less. I'd
treat it as opaque - the SNOR_ID() can now have an arbitrary length -
but I would mention that this *typically* has the form of
<1 byte mfr id> <2 byte flash part id>

I.e.
@bytes: the bytes returned by the flash when issuing command 9F.
         Typically, the first byte is the manufacturer ID code (see
         JEP106) and the next two bytes are a flash part specific ID.

I just moved the description from flash_info :p

As far as I know, this isn't really specified at all, is it? I couldn't
even find that the "read jedec id" command 9F is specified anywhere. Do
you know more?

Also the first three bytes is also wrong. It might be more or less. I'd
treat it as opaque - the SNOR_ID() can now have an arbitrary length -
but I would mention that this *typically* has the form of
<1 byte mfr id> <2 byte flash part id>

I.e.
@bytes: the bytes returned by the flash when issuing command 9F.
         Typically, the first byte is the manufacturer ID code (see
         JEP106) and the next two bytes are a flash part specific ID.

The id is the first one on purpose, because that's our main
key to the entry. I couldn't swap the properties in flash_info
yet because the old entry style used also positional parameters,
i.e. the first entry was always the name.

keep the first entry, to have the name backward compatible. It's not a
hard rule to have the name backward compatible, but if we can, let's
keep it.

Re: [PATCH v2 00/41] mtd: spi-nor: clean the flash_info database up

[Tudor Ambarus]

That's wonderful work, Michael, thanks!

Please specify in the cover letter the flashes with which you tested the
series, we need some sanity checks.

Apart of that, please address the small comments and resend, I'd like to
have this integrated at -rc1 so that we give time to users to spot bugs
and to still have reasonable amount of time to fix them, if any.

Cheers,

the condition looks broken. the method returns bool, but here you return
size_t probably. And when size is zero one shall parse sfdp, not the
other way around.

maybe return (nor->info->size == 0)?

the condition looks broken. the method returns bool, but here you return
size_t probably. And when size is zero one shall parse sfdp, not the

maybe return (nor->info->size == 0)?

As mentioned in my first reply, you're fine with keeping the id
first? After this series, we can swap the name and id members in
struct flash_info.

For all the other members, they should be used consistently. So
we could also swap the members in flash_info.
