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.

Best regards,
