A lot of extra configuration information was left over in the Marvell serdes and DDR3 initialization code for boards that U-boot does not support. Remove this extra config information, and the concept of fixing up board topologies with information loaded from an EEPROM. If this needs to be done, it should be handled in the board file, not in core code.
