But why even _bother_ with crazy resource widths like 16?
Absolutely nobody wants those, even if they could use it?
So the default is all the wrong way around. Make the defaults the sane
ones: 04x for IO, and 08x for MMIO, and then see if anybody wants anything
else. I seriously doubt they do. The whole ".. but but sparc" argument
seems to be entirely based on the total mis-conception of truncation that
has no relevance.
