Hi: York
1, There is an issue for sdk2.0 kernel that the nor-flash can't be probed . we can fix it as follow:
$make menuconfig
x -> Device Drivers x -> Memory Technology Device (MTD) support x -> RAM/ROM/Flash chip drivers x -> Flash chip driver advanced configuration options x -> Flash cmd/query data swapping x x ( ) NO x x (X) BIG_ENDIAN_BYTE x x ( ) LITTLE_ENDIAN_BYTE
Enable BIG_ENDIAN_BYTE .
2, The spi-nor flash can working on ls1043aqds , and I use the sdk2.0 kernel (ce5a3841f3). [ 1.598954] m25p80 spi0.0: n25q128a11 (16384 Kbytes) [ 1.603923] 4 cmdlinepart partitions found on MTD device spi0.0 [ 1.609842] Creating 4 MTD partitions on "spi0.0": [ 1.614624] 0x000000000000-0x000000100000 : "uboot" [ 1.624205] ftl_cs: FTL header not found.

Add and share the the MTD partition scheme with kernel by defualt
bootargs.
And add the "mtdparts" env.

Wenbin,
A related question regarding MTD, how do you make NOR MTD device working on these boards (ls1043aqds and ls1043ardb)? This is a common file for both RDB and QDS. I presume you have verified on both. I have nand working on both, spi-nor working on rdb only. I don't have NOR working on either of them. It may be not a U-Boot issue though.
