NAME
       nand_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.
