This is the original FRV file's copyright notice:

; Fujitsu FRV CPU description.  -*- Scheme -*-
; Copyright (C) 2000, 2001 Red Hat, Inc.
; This file is part of CGEN.
; See file COPYING.CGEN for details.

And this is the exception clause, from COPYING.CGEN, that I understand 
some people are lobying to have added to the standard GPL being applied 
to the .cpu files being contributed:

I think the opening sentence says it all.
