By the by, you may have to decompile the given board file blob, edit that source, then recompile. To get this to work. The last time I downloaded Robert's git for the board overlays, and tried to compile an edited file from those sources. The board would not boot. But decompiling the existing, and working board file blob, editing that source, then recompiling worked. YMMV.
