From 8cff93a1b62a2472d027f679d5877e58cc03a07f Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Sat, 14 Apr 2012 15:26:33 +0000 Subject: target-arm: Move A9 config_base_address reset value to ARMCPU Move the A9 config_base_address cp15 register reset value to ARMCPU. This should become a QOM property so that the Highbank board can set it without having to pull in cpu-qom.h, but at least this avoids the implicit dependency on reset ordering that the previous workaround had.
