NAND_READ_PAGE_HWECC(9) Internal Functions Provided NAND_READ_PAGE_HWECC(9)NAMEnand_read_page_hwecc_oob_first - [REPLACEABLE] hw ecc, read oob first
SYNOPSIS
int nand_read_page_hwecc_oob_first(struct mtd_info * mtd,
struct nand_chip * chip,
uint8_t * buf, int oob_required,
int page);
ARGUMENTS
mtd
mtd info structure
chip
nand chip info structure
buf
buffer to store read data
oob_required
caller requires OOB data read to chip->oob_poi
page
page number to read
DESCRIPTION
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.
