From e8070a23a8f9f6fa28ac1dcb4399c11492f18b10 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 20 Jun 2012 11:57:08 +0000 Subject: target-arm: Remove old cpu_arm_set_cp_io infrastructure All the users of cpu_arm_set_cp_io have been converted, so we can remove it and the infrastructure it used.
