commit 1fcf72bf578e1990c1e1057ea6cbe9d5ee1c7eee Author: Patrick Georgi pgeorgi@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).
