Sorry I don't know anything about that particular board either.

Where is your environment supposed to be stored? If you are booting
from NAND or MMC then you could store it there. There are various
CONFIG_ENV_IS_IN_... variables to define depending on where you want
the environment. The README file lists each of these and explains how
to use them. You also need to define CONFIG_CMD_SAVEENV or perhaps
better #include <config_default.h>.
