MX35LF2G14AC host ecc, lichee/brandy-2.0/u-boot-2018/drivers/mtd/awnand/spinand/physic/id.c
MX35LF2G14AC的ECC参数怎么写？
{
.Model = "MX35LF2G14AC",
.NandID = {0xc2, 0x20, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff},
.DieCntPerChip = 1,
.SectCntPerPage = 4,
.PageCntPerBlk = 64,
.BlkCntPerDie = 2048,
.OobSizePerPage = 64,
.OperationOpt = SPINAND_QUAD_READ | SPINAND_QUAD_PROGRAM |
SPINAND_DUAL_READ,
.MaxEraseTimes = 65000,
//.EccFlag = HAS_EXT_ECC_STATUS,
.EccType = BIT4_LIMIT5_TO_8_ERR9_TO_15,
//.EccProtectedType = SIZE16_OFF4_LEN4_OFF8,
.EccProtectedType = SIZE512_OFF16_LEN4_OFF32,
.BadBlockFlag = BAD_BLK_FLAG_FIRST_2_PAGE,
},

改成
{
.Model = "MX35LF2G14AC",
.NandID = {0xc2, 0x20, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff},
.DieCntPerChip = 1,
.SectCntPerPage = 4,
.PageCntPerBlk = 64,
.BlkCntPerDie = 2048,
.OobSizePerPage = 64,
.OperationOpt = SPINAND_QUAD_READ | SPINAND_QUAD_PROGRAM |
SPINAND_DUAL_READ,
.MaxEraseTimes = 65000,
.EccFlag = HAS_EXT_ECC_SE01, // 需要外部ECC支持
.EccType = BIT4_LIMIT5_TO_7_ERR8_LIMIT_12, // 4位ECC能力
.EccProtectedType = SIZE16_OFF4_LEN8_OFF4, // 数据保护布局
.BadBlockFlag = BAD_BLK_FLAG_FIRST__PAGE,
},

@huali 在 host ECC nand flash怎么支持中说：

.EccType = BIT4_LIMIT5_TO_8_ERR9_TO_15,
.EccProtectedType = SIZE512_OFF16_LEN4_OFF32,
.BadBlockFlag = BAD_BLK_FLAG_FIRST_2_PAGE,
.EccFlag、.EccType 、.EccProtectedType、.BadBlockFlag 该怎么写，谁有文档
