2020-05-31	mtd: spi-nor: winbond: Fix 4-byte opcode support for w25q256	Mantas Pucka	1	-0/+6
	There are 2 different chips (w25q256fv and w25q256jv) that share the same JEDEC ID. Only w25q256jv fully supports 4-byte opcodes. Use SFDP header version to differentiate between them. Fixes: 10050a02f7d5 ("mtd: spi-nor: Add 4B_OPCODES flag to w25q256") Signed-off-by: Mantas Pucka <mantas@8devices.com> Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com>
2020-05-30	mtd: spi-nor: sfdp: prepare BFPT parsing for JESD216 rev D	Pratyush Yadav	1	-2/+3
	JESD216 rev D makes BFPT 20 DWORDs. Update the BFPT size define to reflect that. The check for rev A or later compared the BFPT header length with the maximum BFPT length, BFPT_DWORD_MAX. Since BFPT_DWORD_MAX was 16, and so was the BFPT length for both rev A and B, this check worked fine. But now, since BFPT_DWORD_MAX is 20, it means this check will also stop BFPT parsing for rev A or B, since their length is 16. So, instead check for BFPT_DWORD_MAX_JESD216 to stop BFPT parsing for the first JESD216 version, and check for BFPT_DWORD_MAX_JESD216B for the next two versions.

2020-03-16	mtd: spi-nor: Move SFDP logic out of the core	Tudor Ambarus	1	-0/+98
	It makes the core file a bit smaller and provides better separation between the SFDP parsing and core logic. Keep the core.h and sfdp.h definitions private in drivers/mtd/spi-nor/. Both expose just the definitions that are required by the core and manufacturer drivers. None of the SPI NOR controller drivers should include them.
