From d1d890edace65721e9a7582545c943f67f500709 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 6 Jul 2005 23:06:03 +0100 Subject: [PATCH] ARM: 2789/1: Enable access to both CP10 and CP11 on ARMv6 Patch from Catalin Marinas The VFP instructions trigger undefined exceptions because the access to CP11 is disabled (only CP10 is currently enabled by the kernel). The patch fixes this problem.
