Are they going to be the same on all boards?  We let the board determine 
the environment location for other types of storage.

How about just using CONFIG_ENV_ADDR/CONFIG_ENV_SIZE?  On boards that 
must dynamically support multiple possibilities, define it as an 
expression that returns the right thing.
