Usage: store store init flag store read name addr off|partition size read 'size' bytes starting at offset 'off' to/from memory address 'addr', skipping bad blocks. store write name addr off|partition size write 'size' bytes starting at offset 'off' to/from memory address 'addr', skipping bad blocks. store rom_write add off size. write uboot to the boot device store erase boot/data: erase the area which is uboot or data store erase partition <partition_name>: erase the area which partition in u-boot store erase dtb store erase key store disprotect key store rom_protect on/off store scrub off|partition size scrub the area from offset and size store dtb iread/read/write addr <size> read/write dtb, size is optional store key read/write addr <size> read/write key, size is optional
