How to enable DDR2 and NAND-boot by QSB u-boot?

[HuiShao]

Our customized design is based on QSB but with 256MB Micron MT47H64 DDR2 memory and supposed to boot from 256MB MT29F2G NAND.

Is anybody here who can help on how to re-configure or customize LOCO version of u-boot for the SDRAM/NAND? I went through some documents, seems like DCD is one of the thing needs updating.

Thanks in advance!

Many thanks!

As for NAND - the next files are involved (and may be are needed to be changed) :

uboot\drivers\mtd\nand\nand_ids.c
uboot\drivers\mtd\nand\nand_base.c
uboot\drivers\mtd\nand\nand_device_info.c
