Instead of using off-the-tree .dts files for ARC boards we're switching to use in-tree ones. And for that to work properly we apply upstream patch that adds currently missing "model" property. Upstream patch and discussion could be found here: http://lists.infradead.org/pipermail/linux-snps-arc/2016-August/001394.html Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Jonas Gorski <jonas.gorski@gmail.com> Cc: John Crispin <john@phrozen.org>
