In the latest JEDEC standard (JESD216F), there are now bitfields in the 4 byte address instruction table for 1S-1S-8S and 1S-8S-8S modes
This patchset adds support for checking the 4BAIT for these modes, along with additional NO_SFDP_FLAGS to support enabling these new modes
v2: Move page program commands into sfdp.c instead of core.c, as this appears to conform more closely with spi-nor paradigm. Page program buswidth appears to be automatically determined, so let's follow suit and do the same.
Nathan Barrett-Morrison (3): mtd: spi-nor: Extend SFDP 4byte address instruction lookup table with new octal modes as per JEDEC JESD216F mtd: spi-nor: Add additional octal-mode flags to be checked during SFDP mtd: spi-nor: Add support for IS25LX256 operating in 1S-1S-8S octal read mode
