Happy hacking!

Just "ignore" these settings - use a standard U-Boot environment in
flash, and add some custom functions to initialize critical
environment variables (like serial number, MAC address, ...) from
your proprietary EEPROM if they don't exist yet. See for example the
code in board/tqm8xx/load_sernum_ethaddr.c which reads such data from
a vendor specific location in flash.
