From fa08d39517773882b07965ca4330777c6d6697ae Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 11 Apr 2014 17:09:45 +0200 Subject: PPC 85xx: Add qemu-ppce500 machine For KVM we have a special PV machine type called "ppce500". This machine is inspired by the MPC8544DS board, but implements a lot less features than that one. It also provides more PCI slots and is supposed to be enumerated by device tree only. This patch adds support for the generic ppce500 machine and tries to rely solely on device tree for device enumeration.
