From d4bee5d0fb8b8775af2a0da356fce9d3bf8104bb Mon Sep 17 00:00:00 2001
From: Francis Rowe <info@gluglug.org.uk>
Date: Mon, 04 May 2015 09:58:54 -0400
Subject: Update coreboot + merge GM45 hybrid GPU patches

Also add power_on_after_fail to X200 and others (prevents the bug
where the system would boot when connecting the AC adapter)
(option in menuconfig to use CMOS/nvram settings is now enabled)

Also NetDCDC is now the default USB debug dongle used (compatible
with the BBB rev C).

Add two new methods for managing coreboot configs:
./build config corebootreplace
./build config corebootmodify
