SPI NOR core changes:
- move all the manufacturer specific quirks/code out of the core, to make the core logic more readable and thus ease maintenance. - move the SFDP logic out of the core, it provides a better separation between the SFDP parsing and core logic. - trim what is exposed in spi-nor.h. The SPI NOR controllers drivers must not be able to use structures that are meant just for the SPI NOR core. - use the spi-mem direct mapping API to let advanced controllers optimize the read/write operations when they support direct mapping. - add generic formula for the Status Register block protection handling. It fixes some long standing locking limitations and eases the addition of the 4bit block protection support. - add block protection support for flashes with 4 block protection bits in the Status Register. SPI NOR controller drivers changes: - the mtk-quadspi driver is replaced by the new spi-mem spi-mtk-nor driver. Merge tag 'mtk-mtd-spi-move' into spi-nor/next to avoid conflicts. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEHUIqys8OyG1eHf7fS1VPR6WNFOkFAl55/fwACgkQS1VPR6WN FOmEuggAg3MFX00BF/VV/8uUs4yhgBgPVdRMpzuZFFxKEeX4ijCUD/HBCPMQeIST Q85dlMxnQCpJejDlqYF5+7BlZp8hVNXd2hpIFP8MwPm+vnyciyLRZf+WP/zW20OW 5nWtNWf7vqjF66QxfdCThe0DrFjGsr7cijJ0ZU0JzAY2e26ANtOcMbrfUlFVPt03 l6H3gsuHcqfzZV9uuAZytsRMTpuPc3sNUO224SqM7QeGapLrGBdGU49FILPc7Rwi 5ATX0UaSUXqXyqzJB7vB9ZLxhaZyZUei/Uqooi8iE4sMTUR8+GXoTrght+Fy2yxw xUAtpOMOg/PqDdINTTZqJOmQ0ab2sA== =hb3Q -----END PGP SIGNATURE----- Merge tag 'spi-nor/for-5.7' into mtd/next SPI NOR core changes: - move all the manufacturer specific quirks/code out of the core, to make the core logic more readable and thus ease maintenance. - move the SFDP logic out of the core, it provides a better separation between the SFDP parsing and core logic. - trim what is exposed in spi-nor.h.
