From ac643e0363b4fe32e2742ede8084fc9999bd0bfb Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 17 Jan 2016 16:11:30 -0700 Subject: x86: Bring up northbridge, pch and lpc after the CPUs These devices currently need to be inited early in boot. Once we have the init in the right places (with each device doing its own init and no problems with ordering) we should be able to remove this. For now it is needed to keep things working.
