From 276229d2a98975d0cca9637d1dfee6a9876b54c5 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Wed, 10 Sep 2014 22:39:19 +0200 Subject: [PATCH] MIPS: lantiq: add support for xrx200 firmware depending on soc type MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit VR9 needs different firmware files for the various phy/soc revisions. Some boards are ship with older and newer SoC revisions. To be able to boot a single image on all versions we need to define both firmware files inside the devicetree.
