[U-Boot] [PATCH 3/5] da830: add support for NAND boot mode

I am just curious, since this patch adds NAND boot mode for the
First time in denx git, how this affects you? Are you storing
ENV variables in NAND during some other boot mode? In fact we are
Adding other boot mode in this patch set. How come you are using
Denx tree to flash bios on your da830 board?

Regards,
Nag
