From 0fdda107e10133583f31c72326959555bfb61042 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Sat, 3 Sep 2005 15:56:06 -0700 Subject: [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.
