Clean spi_nor_scan() and the flash parameters initialization code.
Reworked how the flags are handled for the flash_info entries.
Tested all the flashes from patch set.
Changes in v5:
- new patch 0001-mtd-spi-nor-Fix-mtd-size-for-s3an-flashes.patch
- update comment from
'[PATCH v4 02/13] mtd: spi-nor: Introduce spi_nor_set_mtd_info()',
s/'No mtd_info fields are used up to this point.'/
'No mtd_info fields should be used up to this point.'
- collect R-b tags
Changes in v4:
- new patch:
"mtd: spi-nor: core: Don't use mtd_info in the NOR's probe sequence of calls"
- move spi_nor_post_sfdp_fixups() in drivers/mtd/spi-nor/sfdp.c
- Reworked flash_info flags. nor->info->flags are split in new flash_info
members: parse_sfdp, flags, no_sfdp_flags, fixup_flags and mfr_flags.
- remove roll-back mechanism for flashes that use PARSE_SFDP.
- dropped R-b tags where the new version of the patch modified how things
are handled
- v4 changes log in each commit after ---
Changes in v3:
- move late_init() in struct spi_nor_fixups and update patches accordingly.
R-b tags were dropped.
- new patch "mtd: spi-nor: sst: Get rid of SST_WRITE flash_info flag"
moves manufacturer specific flag out of the core.
- update methods description to make it clear who sets when
- introduce flash_info flag masks to make it clear when one should be set.
- rework "parse SFDP first idea".

I've done it in a separate patch because this can be backported as a fix.

Move the mtd_info init the last thing in the spi_nor_scan(), so that we avoid superfluous initialization of the mtd_info fields in case of errors. While here use common naming scheme for functions that are setting mtd_info fields: s/spi_nor_register_locking_ops/spi_nor_set_mtd_locking_ops s/spi_nor_otp_init/spi_nor_set_mtd_otp_ops The functions names are self explanatory, get rid of the comment for the OTP function.

Split them in four categories and a bool: 1/ FLAGS: flags that indicate support that is not defined by the JESD216 standard in its SFDP tables. 2/ NO_SFDP_FLAGS: these flags are used when the flash does not define the SFDP tables. These flags indicate support that can be discovered via SFDP. Used together with SPI_NOR_SKIP_SFDP flag. 3/ FIXUP_FLAGS: flags that indicate support that can be discovered via SFDP ideally, but can not be discovered for this particular flash because the SFDP table that indicates this support is not defined by the flash. In case the table for this support is defined but has wrong values, one should instead use a post_sfdp() hook to set the SNOR_F equivalent flag. 4/ MFR_FLAGS: manufacturer private flags. Used in the manufacturer fixup hooks to differentiate support between flashes of the same manufacturer. 5/ PARSE_SFDP: sets info->parse_sfdp to true. All flash_info entries that support SFDP should be converted to set info->parse_sfdp to true. SPI NOR flashes that statically declare one of the SPI_NOR_{DUAL, QUAD, OCTAL, OCTAL_DTR}_READ flags and do not support the RDSFDP command are gratuiously receiving the RDSFDP command in the attempt of parsing the SFDP tables. It is not desirable to issue commands that are not supported, so introduce PARSE_SFDP to help on this situation. New flash additions/updates should be declared/updated to use either PARSE_SFDP or SPI_NOR_SKIP_SFDP. Once all the flash_info entries are converted to use SPI_NOR_SKIP_SFDP or PARSE_SFDP, we can get rid of the SPI_NOR_SKIP_SFDP flag and use just the bool nor->info->parse_sfdp to determine whether to parse SFDP or not. SPI_NOR_SKIP_SFDP flag is kept just as a way to differentiate whether a flash is converted to the new flags logic or not. Support that can be discovered when parsing SFDP should not be duplicated by explicit flags at flash declaration. All the flash parameters will be discovered when parsing SFDP. Sometimes manufacturers wrongly define some fields in the SFDP tables. If that's the case, SFDP data can be amended with the fixups() hooks. It is not common, but if the SFDP tables are entirely wrong, and it does not worth the hassle to tweak the SFDP parameters by using the fixups hooks, or if the flash does not define the SFDP tables at all, then statically init the flash with the SPI_NOR_SKIP_SFDP flag and specify the rest of flash capabilities with the flash info flags. With time, we want to convert all flashes to use PARSE_SFDP and stop triggering the SFDP parsing with the SPI_NOR_{DUAL, QUAD, OCTAL*}_READ flags. Getting rid of the SPI_NOR_{OCTAL, OCTAL_DTR}_READ trigger is easily achievable, the rest are a long term goal. Manufacturer specific flags like USE_CLSR, USE_FSR, SPI_NOR_XSR_RDY, will be removed in a future series. No functional changes intended in this patch.

This moves the setting of SNOR_F_READY_XSR_RDY and SNOR_F_HAS_LOCK late in the init call, without any functional change expected. The rest of the flags were already set after the spi_nor_init_params().

Introduce a dedicated function for setting the fixup_flags and emphasise when those flash_info flags should be set: when the SNOR_F_4B_OPCODES/SNOR_F_IO_MODE_EN_VOLATILE setttings can not be discovered by SFDP for this particular flash because the SFDP table that indicates this support is not defined in the flash. In case the table for his support is defined but has wrong values, one should instead use a post_sfdp() hook to set the SNOR_F equivalent flag. No functional change intended in this patch.

Keep the old way of initializing the flash, until all the flashes are converted to use either PARSE_SFDP or SPI_NOR_SKIP_SFDP. Flashes that declare PARSE_SFDP do not have a roll-back mechanism because if spi_nor_parse_sfdp() returns an error it means that either BFPT is not supported, thus SFDP is not supported and the user didn't correctly declared the flash_info entry, or some memalloc failed. Either way we should return an error. The rest of the SFDP tables are optional, if one of the optional SFDP tables fails, we just continue. We would like to get rid of the default_init() hook, so the spi_nor_manufacturer_init_params() is not called in the new sequnce of flash initialization that is based solely on SFDP. Split spi_nor_info_init_params() in spi_nor_init_default_params() and spi_nor_no_sfdp_init_params(). spi_nor_init_default_params() is called for all the flashes regardless if they support SFDP or not. spi_nor_no_sfdp_init_params() is called just for the flashes that do not define SFDP and initializes parameters and setting solely based on flash_info data.
