Ah well for such a simple patch it turns out more complicated than thought :-)
Will do as soon as there is agreement on a name which does not seem that
easy...

As far as i remember there are different de0 and different sockit boards, so
the name does not seem to be as concise? I don't care but i would say that
de0-nano-soc is the most concise and easier to search for than atlas which
might turn up more false postives?
But as long as there is a more selective name than cyclone5 everthing is fine
with me.
