I believe these should go to board specific header file such as
socfpga_cyclone5 and socfpga_socrates. These are HW configuration
handoff files and different from board to board.

Just a quick comments. In newer version SPL at rocketboard.org, we won't
need to specify the size. It will be calculated based on HW registers.
We will change this together with SPL SDRAM patch.

Same as above. We need to retain the handoff path in board specific
header file instead common.
