U-BOOT启动内核中出现的问题

sxbo

U-BOOT终于可以启动了,可又出现另外一问题:
在内核中总是冒出:Reading data from NAND FLASH without ECC is not recommended(为了让u-boot从NAND flash启动,我在内核中加入了语句:chip->eccmode=NAND_ECC_NONE)

启动过程如下:
..........................
...........................
TCP: Hash tables configured (established 1024 bind 1024)
TCP reno registered
TCP bic registered
NET: Registered protocol family 1
Reading data from NAND FLASH without ECC is not recommended
VFS: Mounted root (cramfs filesystem) readonly.
Mounted devfs on /dev
Freeing init memory: 92K
Reading data from NAND FLASH without ECC is not recommended
Reading data from NAND FLASH without ECC is not recommended

请教这如何消除Reading data from NAND FLASH without ECC is not recommended老出现这现象啊/
谢谢

把ECC干掉：
drivers/mtd/nand/s3c2410.c的s3c2410_nand_init_chip()函数的最后一行加入：

chip>eccmode = NAND_ECC_NONE;
应该可以解决
