Dear Tom Rini,

Yes, board rev detection to know how to configure SDRAM.
I don't consider this a valid reason (reading the SPD EEPROM would be such a reason). In almost all other cases it should be suffucient to configure the maximum number of memory banks and the maximum size of the memory banks and then use get_ram_size() to determine the actual amount of memory and to correctly initialize the memory controller.
Note that I don't insist on any changes to existing code here. This is just a recommendation which you may (or may not) consider for any future ports / implementations.
Best regards,
Wolfgang Denk
