From 00ce25c6dcdae5582ae4be37147ab33678adc995 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Fri, 25 Apr 2014 11:22:32 +0200 Subject: Add devicetree source files as of Linux-3.15-rc2 This adds the Linux dts files to barebox. The dts files are generated from Ian Campbells device-tree-rebasing.git: git://xenbits.xen.org/people/ianc/device-tree-rebasing.git The dts are found in dts/ in the barebox repository and will be updated from upstream regularly, probably for each upstream -rc. To keep the synchronization with upstream easy no changes to the original files are allowed under dts/. Instead changes to upstream dts files will be done using overlays in arch/$ARCH/dts/.
