## ECC selection constants

Use these constants to select the ECC algorithm.

    /* No ECC. Usage is not recommended ! */
    #define NAND_ECC_NONE		0
    /* Software ECC 3 byte ECC per 256 Byte data */
    #define NAND_ECC_SOFT		1
    /* Hardware ECC 3 byte ECC per 256 Byte data */
    #define NAND_ECC_HW3_256	2
    /* Hardware ECC 3 byte ECC per 512 Byte data */
    #define NAND_ECC_HW3_512	3
    /* Hardware ECC 6 byte ECC per 512 Byte data */
    #define NAND_ECC_HW6_512	4
    /* Hardware ECC 6 byte ECC per 512 Byte data */
    #define NAND_ECC_HW8_512	6
