Overview

Hardware ECC for large page chips, require OOB to be read first. For this ECC mode, the write_page method is re-used from ECC_HW. These methods read/write ECC from the OOB area, unlike the ECC_HW_SYNDROME support with multiple ECC steps, follows the “infix ECC” scheme and reads/writes ECC from the data area, by overwriting the NAND manufacturer bad block markings.
