I don't think it's bogus.  I thought it was setting up the IO range to be
decoded.  It lets accesses go to the hardware in that range (all of PCI.)

The problem is that since there's no corresponding resource, we never take
care of it later.

At what stage do we check the resource tree and make sure that all of the
resources fit inside a parent's resource so that they're reachable?  What
about subtractive decoding?
