This is series v4 for SPI-NOR support on SiFive FU540 platform with HiFive Unleashed board.
Here is the previous version changes[1].
All patches on top of u-boot-spi/master.
Thanks for posting v4 for spi-nor support. Tested the series above u-boot-spi/master on HiFive Unleashed and was able to verify it for both spi-nor and mmc Additionally just confirmed the opcodes nor is configured with post spi_nor_scan: ====================================================== [QUAD mode in dt with spi-tx-bus-width: <4>] pp opcode = 0x34 [QUAD MODE] read opcode = 0x6c [QUAD MODE] erase opcode = 0x21
SPI-NOR: 1. erase entire flash: Pass 2. write entire flash: Pass 3. read entire flash: Pass 4. cmp 32MiB read back data: Pass 5. MMC: Booted Linux and dtb from mmc (so as to confirm data integrity from mmc) ================================================================= [SPI MODE in dt with spi-tx-bus-width: <1> ] pp opcode = 0x12 [SPI MODE] read opcode = 0xc [SPI MODE] erase opcode = 0x21
SPI-NOR: 1. erase entire flash: Pass 2. write entire flash: Pass 3. read entire flash: Pass 4. cmp 32MiB read back data: Pass 5. MMC: Booted Linux and dtb from mmc (so as to confirm data integrity from mmc)
