From c2ad284412e495318d3b6a338ffdbbe42a594b97 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Mon, 11 Feb 2013 17:30:30 -0600 Subject: arm: socfpga: Add new device tree source for actual socfpga HW Up to this point, support for socfpga has only been on a virtual platform. Now that actual hardware is available, we add the appropriate device tree source files.
