805  * onenand_recover_lsb - [Flex-OneNAND] Recover LSB page data
810  * MLC NAND Flash cell has paired pages - LSB page and MSB page. LSB page has
811  * lower page address and MSB page has higher page address in paired pages.
812  * If power off occurs during MSB page program, the paired LSB page data can
813  * become corrupt. LSB page recovery read is a way to read LSB page though page
814  * data are corrupted. When uncorrectable error occurs as a result of LSB page
815  * read after power up, issue LSB page recovery read.
