Jagan Teki 286bcdb40f sifive: fu540: Enable spi-nor flash support ... HiFive Unleashed A00 support is25wp256 spi-nor flash, So enable the same and add test result log for future reference. Tested on SiFive FU540 board. Thanks to Sagar for various use cases and tests. [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 [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.
