From 357c9c1f07d4546bc3fbc0fd1044d96b114d14ed Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 4 May 2012 12:04:26 +0100 Subject: ARM: Remove support for ARMv3 ARM610 and ARM710 CPUs This patch removes support for ARMv3 CPUs, which haven't worked properly for quite some time (see the FIXME comment in arch/arm/mm/fault.c). The only V3 parts left is the cache model for ARMv3, which is needed for some odd reason by ARM740T CPUs, and being able to build with -march=armv3, which is required for the RiscPC platform due to its bus structure.
