Aren't static DDR configurations now handled in a board-specific
source file?  Look at board/freescale/corenet_ds/p4080ds_ddr.c

No need for the #ifdef here.  CONFIG_SYS_I2C_EEPROM_NXID is not used
in any Makefile.

Not 0x57?  That's where the NXID EEPROM almost always is.

These look like functions that shouldn't be in board-specific code.
