From dec9c2d4306d7b4f8ffff482ac42dc468ed2a61d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Thu, 29 Mar 2012 04:50:31 +0000 Subject: target-arm: Minimalistic CPU QOM'ification MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce only one non-abstract type TYPE_ARM_CPU and do not touch cp15 registers to not interfere with Peter's ongoing remodelling. Embed CPUARMState as first (additional) field of ARMCPU. Let CPUClass::reset() call cpu_state_reset() for now.
