+          Enable the MTD support for spi flash layer, this adapter is for
+         translating mtd_read/mtd_write commands into spi_flash_read/write
+         commands. It is not intended to use it within sf_cmd or the SPI
+         flash subsystem. Such an adapter is needed for subsystems like
+         UBI which can only operate on top of the MTD layer.
