[PATCH] mips: remove VR4181 support
There seem to be no more users or interest in the NEC Osprey evaluation system for the NEC VR4181 SOC which is an old part anyway, so remove the code. More information on the Osprey can be found at http://www.linux-mips.org/wiki/Osprey. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
