This patch now uses the correct ECC byte order (Smart Media - SMC) to be used on the 4xx NAND FLASH driver. Without this patch we have incompatible ECC byte ordering to the Linux kernel NDFC driver.
Please note that we also have to enable CONFIG_MTD_NAND_ECC_SMC in drivers/mtd/nand/nand_ecc.c for correct operation. This is done with a seperate patch.
