Changes since v5: - Removed 256Mb and 4Gb parts support - Fixed register offset issue in spansion_quad_enable_volatile() - Added spi_nor_default_ready() and moved existing code into it - Separated spansion_sr_read() to new patch - Renamed spansion_overlaid_erase() to spansion_non_uniform_erase() and changed the implementation to issue the proper erase command based on the address - Added s25hx_t_erase_non_uniform() - Changed mtd.writesize and mtd.flags in s25hx_t_setup() - Fixed page size and erase size issues in s25hx_t_post_bfpt_fixup() Changes since v4: - Added Read/Write Any Register support - Added the ->ready() hook to support multi-die package parts - Added S25HL02GT/S25HL04GT/S25HS02GT/S25HS04GT support Changes since v3: - Split into multiple patches Changes since v2: - Fixed typo in comment for spansion_overlaid_erase() - Fixed expressions for addr and len check in spansion_overlaid_erase() - Added device ID check to make the changes effective for S25 only - Added nor->setup() and fixup hooks based on the following patches https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-7-p.yadav at ti.com/ https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-8-p.yadav at ti.com/ https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-9-p.yadav at ti.com/ Takahiro Kuwano (10): mtd: spi-nor: Add Cypress manufacturer ID mtd: spi-nor-ids: Add Cypress s25hl-t/s25hs-t mtd: spi-nor-core: Add support for Read/Write Any Register mtd: spi-nor-core: Add support for volatile QE bit mtd: spi-nor-core: Add the ->ready() hook mtd: spi-nor-core: Read status by Read Any Register mtd: spi-nor-core: Add non-uniform erase for Spansion/Cypress mtd: spi-nor-core: Add Cypress manufacturer ID in set_4byte mtd: spi-nor-core: Add fixups for Cypress s25hl-t/s25hs-t mtd: spi-nor-tiny: Add fixups for Cypress s25hl-t/s25hs-t drivers/mtd/spi/spi-nor-core.c | 345 ++++++++++++++++++++++++++++++++- drivers/mtd/spi/spi-nor-ids.c | 27 +++ drivers/mtd/spi/spi-nor-tiny.c | 90 +++++++++ include/linux/mtd/spi-nor.h | 10 + 4 files changed, 471 insertions(+), 1 deletion(-) -- 2.25.1
