811 UBI is a software layer above MTD layer which admits use of LVM-like
812 logical volumes on top of MTD devices, hides some complexities of
813 flash chips like wear and bad blocks and provides some other useful
814 capabilities. Please, consult the MTD web site for more details
815 (www.linux-mtd.infradead.org). Activate this option if you want
816 to use U-Boot UBI commands.
