Tested on Xilinx Zynq-7000 FPGA board.
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.yad... https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-8-p.yad... https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-9-p.yad...
