[v4,00/13] mtd: spi-nor: Clean params init

Message

Tudor Ambarus Nov. 22, 2021, 9:50 a.m. UTC

Clean spi_nor_scan() and the flash parameters initialization code. 
Tested all the flashes from patch set. Reworked how the flags are
handled for the flash_info entries.

Changes in 4:
- 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

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".
- v4 changes log in each commit after ---
