From be13cc7a352b74412374a554a15b32b105f6706b Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 31 Aug 2010 00:22:28 +0200 Subject: [PATCH] PPC: Qdev'ify e500 pci The e500 PCI controller isn't qdev'ified yet. This leads to severe issues when running with -drive. To be able to use a virtio disk with an e500 VM, let's convert the PCI controller over to qdev.
