Happy hacking!
The problem is, that the kind of changing variables in the EEPROM should be the same (compatibility to the current modules). That means we have to use the same EEPROM structure, for e.g. the MAC address, as before.
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.
