From 192fbc20258c79e3f776a5ce6cea4654376f5af6 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Tue, 22 Sep 2015 11:12:13 -0700 Subject: [PATCH] MIPS: CPS: Skip Config1 presence check The Config1 register is architecturally defined as required, and is thus present in all systems which may make use of cps-vec.S. Skip the check for its presence via the Config.M bit.
