Merge tag 'spi-nor/for-6.4' into mtd/next
SPI NOR core changes: * introduce Read While Write support for flashes featuring several banks * set the 4-Byte Address Mode method based on SFDP data * allow post_sfdp hook to return errors * parse SCCR MC table and introduce support for multi-chip devices SPI NOR manufacturer drivers changes: * macronix: add support for mx25uw51245g with RWW * spansion: - determine current address mode at runtime as it can be changed in a non-volatile way and differ from factory defaults or from what SFDP advertises. - enable JFFS2 write buffer mode for few ECC'd NOR flashes: S25FS256T, s25hx and s28hx - add support for s25hl02gt and s25hs02gt Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
