Subject: [PATCH 1/5] Pull in recent changes from the main dtc repository. These changes primarily

From: John Bonesio <[email-masked]>
Date: Wed, 17 Nov 2010 15:28:20 -0800

allow multiple device trees to be declared which are merged by dtc. This
feature allows us to include a basic dts file and then provide more information
for the specific system through the merging functionality.
