mtd: nand: omap_elm: use bch_type instead of nibble count to differentiate between BCH4/BCH8/BCH16
ELM hardware engine support ECC error detection for multiple ECC strengths like +------+------------------------+ |Type | ECC syndrome length | +------+------------------------+ |BCH4 | 6.5 bytes = 13 nibbles | |BCH8 | 13 byte = 26 nibbles | |BCH16 | 26 bytes = 52 nibbles | +------+------------------------+ Current implementation of omap_elm driver uses ECC syndrom length (in 'nibbles') to differentiate between BCH4/BCH8/BCH16. This patch replaces it with 'bch_type' Signed-off-by: Pekon Gupta <pekon@ti.com> Reviewed-by: Stefan Roese <sr@denx.de>
