[PATCH 2/3] powerpc/e500: add paravirt QEMU platform

2012-06-27 Thread Scott Wood
This gives the kernel a paravirtualized machine to target, without requiring both sides to pretend to be targeting a specific board that likely has little to do with the host in KVM scenarios. This avoids the need to add new boards to QEMU just to be able to run KVM on new CPUs. As this is the fi
