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

John Bonesio bones at secretlab.ca
Thu Nov 18 10:28:20 EST 2010


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.
