From 5680fafb4d2cdc1d914226ff4d01b9b12ba75097 Mon Sep 17 00:00:00 2001 From: Damien Zammit Date: Fri, 22 Jan 2016 22:12:30 +1100 Subject: [PATCH] nb/intel/x4x: Move to early cbmem Previously with errors in the ram init, early cbmem was disabled. Now that the ram is working correctly, set as early cbmem platform and update all (1) boards to use it.
