This option will provide the generic support for MTD drivers to register themselves with the kernel and for potential users of MTD devices WebUse the MTD interface provided for SPI flash on the EVM to validate the SPI driver interface. The below step copies 8KiB from /dev/mtd2 partition (u-boot env) to /dev/mtd4 partition and reads the 8KiB image from /dev/mtd4 to a file and checks the md5sum. The md5sum of test.img and test1.img should be same.
