From a25bc78e2f8d9f91c6f7d97a3d4a6632bec3c400 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Thu, 13 Aug 2015 00:29:11 -0700 Subject: [PATCH] x86: coreboot: Allow >=4GiB memory bank size Some platforms may have >=4GiB memory, so we need make U-Boot report such configuration correctly when booting as the coreboot payload.
