commit af541b7456c034765e008f702ff8150484b57b71
Author: Patrick Georgi <pgeorgi at chromium.org>
Date:   Sat Jan 28 13:12:09 2017 +0100

    device/dram: use global DIMM_SPD_SIZE Kconfig variable
    
    Also make sure that no board changes behaviour because of that by adding
    a static assert.
    
    TEST=abuild over all builds still succeeds (where it doesn't if
    DIMM_SPD_SIZE isn't set to 128 bytes for boards that use the
    device/dram code).
