Not correcting anything in case of empty ECC data area is not an appropriate strategy, because an uncorrected bit-flip in an empty sector may cause upper layers (namely UBI) fail to work properly. Therefore the approach chosen in Linux kernel and other u-boot mtd drivers has been adopted, where a heuristic implemented by nand_check_erased_ecc_chunk() is used in order to detect and correct empty sectors. Tested with sama5d3_xplained and sam9x60-ek.
