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.
