May I ask WHY you are not comfortable with using the U-Boot
environment? Usually it's a very convenient place to store
configuration data, and a pretty reliable one (especially when you
use redundant environment).

I have seen _way_ more cases where data in EEPROM got lost than data
loss from the environment.
