Using the full blown a8040-db version which might even break a
A7k board does not seem to be a good choice for my taste.
I'm wondering if it doesn't make more sense to use a different
DTS file instead as a "lowest common denominator" for this
default DTS. Either a A70x0 file or perhaps even add a very
small new one, with only serial support?

Thanks,
