This is the new patch. Looking at other parts of devices.txt, obsolete is
sometimes used together with unused. I guess obsolete means this is old interface so
don't use it as much as possible and unused means this is not used at all now.
You remove old memory interface completely in this patch set, so is it better to add
unused, too?
