The code is based on norbert thiel's comment litex-hub/litespi#52 But edited to work with W25Q128JVS flash used in MNT RKX7.
… cmd When shipping MNT RKX7, I pre-flash the SPI flash with a LiteX bitfile for testing. cmd_spiflash had regressed because of changed SPIFLASH defines and didn't offer the write functions anymore. This commit fixes that, and adds convenience functions: - flash_erase_range <offset> <count (bytes)> - flash_from_sdcard <filename> The latter reuses some boot code to copy the contents of the specified file from the boot FAT partition on the SD card to SPI flash (i.e. a bitstream).
