Sorry, I initially deferred it and then didn't get back to it.

The dependency on the .dts changes made me a bit nervous about
taking it, mostly because the changelog fails to explain the
exact dependencies.

This breaks compatibility with existing .dtb files, right?
What I'd like to see here is an explanation about:

- what the upside of breaking compatibility is
- what exactly stops working with an old dtb
- why we don't keep a fallback for handling old dtb files

It would also be helpful to have a separate pull request for
the commits require the new dtb, and the stuff that is unrelated.
