yes, static ddr configurations are handled in board c file, but it
doesn't matter to define those MACROs in header file. But anyway, I've
remove static ddr setting from board file as Scott suggested, so I
should remove above setting in header file.

OK.

It is board specific value, isn't it? P1021MDS does use 0x52 for board eeprom.

Scott replied you. I also think with partial linking, this can be
factored out.
