We recently completed work to implement the entire sh architecture in 
SID starting with the existing sh64 implementation which already existed 
in cpu/ and cgen/cpu and which were nearly identical at the time. No one 
could tell me which one was the master and it appeared that some work 
was in cgen/cpu/ but not in cpu/, so I arbitrarily chose to work in 
cgen/cpu/.

It doesn't matter to us (Red Hat) where the copyright lies for this 
port, so feel free to bring cpu/ up to date and make it the master if 
you please.
