From e30614d51780f27c53b196da793c3fb89f1f620f Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Tue, 4 Nov 2014 15:41:20 +0000 Subject: [PATCH] mips: Set the CP0.Config3.DSP and CP0.Config3.DSP2P bits Set the CP0.Config3.DSP2P bit for the 74kf processor and both that bit and the CP0.Config3.DSP bit for the artificial mips32r5-generic and mips64dspr2 processors. They have the DSPr2 ASE enabled in `insn_flags' and CPUs that implement that ASE need to have both CP0.Config3.DSP and CP0.Config3.DSP2P set or software won't detect its presence.
