This adds very basic device tree files for the Marvell Armada 1500 SoC (Berlin BG2) and the Sony NSZ-GS7 GoogleTV board. Currently, SoC only has nodes for cpus, some clocks, l2 cache controller, local timer, apb timers, uart, and interrupt controllers. The Sony NSZ-GS7 is a GoogleTV consumer device comprising the Armada 1500 SoC above.
