[PATCH] Initial Device Tree system for Snowball
Niklas Hernaeus
niklas.hernaeus at stericsson.com
Sat Mar 3 02:52:47 EST 2012
From: Niklas Hernaeus <niklas.hernaeus at linaro.org>
This is the base system for using Device Tree for Snowball.
The new boardfile is a slightly modified copy of the original board file,
so new Device Tree stuff can simply be added and code removed, while
functionality stays the same.
