Hmmm... we do care about doing 32bit when possible as there are cases
where PIO is the only data tarnsfer mode available (it's ancient at
this point but then again we're talking about pata_platform devices).
Are you saying that the controllers in question here wouldn't care
because they're all 16bit only anyway? Otherwise, we do want to
distinguish them.
Thanks.
