Built-in dtb's are really for legacy bootloader cases where the
bootloader doesn't understand dtbs. Do you have that here?

Plus, I don't see any code here to handle the built-in dtb.

I see it is in patch 2. That means patch 2 won't actually compile. You
should move the devtree.c parts at least and maybe the Makefile
infrastructure part too to patch 2. I don't think you need to split
things up so much, but I'll defer to Arnd on that.
