I don't see any of my comments on v3 addressed or responded to:
http://lists.denx.de/pipermail/u-boot/2010-December/083601.html

NACK.

Hi Scott

thanks the comments, I am working on the nand_boot_jz4740.c now.
I try to using the system nand_boot.c, but it's need sometime.
I will try to send another patch in next two days.

thanks again.
