Subject: [PATCH v3 0/3] mtd: spi-nor: Parse BFPT to determine the 4-Byte Address Mode

Get the 4-Byte Address mode method from BFPT and favor it in the detriment
of the "default" set_4byte_addr_mode method or the methods set by vendors.
This may introduce some regressions if flashes have wrong BFPT data. The
fix is to introduce post_bfpt() hooks and fix where needed. We should let
the core/sfdp do the params initialization, and do vendor specific updates
just where needed.

v3:
- Move the newly introduced BFPT definitions in sfdp.h, as they may be used by
manufacturer drivers to handle flash ID collisions.
- Drop "mtd: spi-nor: sfdp: Keep SFDP definitions private" patch for the same
reason as above
- Collect R-b tags

v2: Drop quad enable patch

Tudor Ambarus (3):
  mtd: spi-nor: Parse BFPT to determine the 4-Byte Address Mode methods
  mtd: spi-nor: Update name and description of the set_4byte_addr_mode
    BFPT methods
  mtd: spi-nor: Favor the BFPT-parsed set_4byte_addr_mode method
