From dc71e254941cf922e4686fc40bf8d77f3ccfe447 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Mon, 29 Jan 2018 10:14:48 +0100 Subject: nb/intel/nehalem: Use the common mrc cache driver The common mrc cache driver allows to save the raminit training results to a separate fmap region which is more manageable than a cbfsfile.
