Hi Alex,


At least I get problems during compile step with above change (I'm
building for rpi2). So are your sure '${B}/arch/arm/boot/dts/overlays'
isn't needed during compile? I tried with changing above from append to
prepand instead and then it worked fine for me (when building 3.18
kernel). 

(from log.do_compile, complete log can be found at:
http://www.technux.se/logs/log.do_compile.4398.fail )
