What probably meant was that I didn't want a bunch of different device
trees for each combination board * hat. An overlay makes a lot more
sense. However, looking through the kernel tree there is a surprising
lack of overlays for hats committed already, so I suspect there is
some sort of policy around overlays already in place.
