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?


Does obsolete also mean "not used anymore"? I don't know. I think we can wait 
for some native
English speakers to comment on this.


Yes. To be honest, I'm still suspecting "unused" doesn't include meaning of 
"removed"...
