Subject: [PATCH 0/5] 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.

This patch set depends on:
