Since v2: Split sync up patches into smaller versions so that its easier for review. Address comments by Jagan and Simon Goldschmidt on v2. Make SPI_FLASH_TINY(read only SF stack) as default for SPL build to offset against size increase due to new code. Since v1: Remove #ifindef __UBOOT__ Add back BAR support, but dont enable as default for all platform (see 10/11 for more details) Enable SPI_FLASH_TINY on boards where there is SPL size constraint as seen on travis ci builds. Drop sf_mtd changes for now as it seems to cause issues. v1: https://patchwork.ozlabs.org/cover/1012146/ Since RFC v2: Fix issues reported by Simon Goldschmidt wrt 4 use of byte addressing opcode Fix issues in compiling SFDP code Re organize file names and Makefile to simply spi-nor-tiny inclusion Remove SPI_FLASH_BAR and SF_DUAL_FLASH as these are no longer used RFC v2: https://patchwork.ozlabs.org/cover/1007589/ Since RFC v1: Add lightweight SPI flash stack for boards with SPL size constraints Provide non DM version of spi-mem Fix build issues on different platforms as reported by travis-ci on v1 RFC v1: https://patchwork.ozlabs.org/cover/1004689/ Background: U-Boot SPI NOR support (sf layer) is quite outdated as it does not support 4 byte addressing opcodes, SFDP table parsing and different types of quad mode enable sequences. Many newer flashes no longer support BANK registers used by sf layer to a access >16MB space. Also, many SPI controllers have special MMIO interfaces which provide accelerated read/write access but require knowledge of flash parameters to make use of it. Recent spi-mem layer provides a way to support such flashes but sf layer isn't using that. This patch series syncs SPI NOR framework from Linux v4.19. It also adds spi-mem support on top. So, we gain 4byte addressing support and SFDP support. This makes migrating to U-Boot MTD framework easier. Tested with few Spansion, micron and macronix flashes with TI's dra7xx, k2g, am43xx EVMs. I dont have access to flashes from other vendors. So, I would greatly appreciate testing on other platforms.
