[Qemu-ppc] [PATCH v2 3/4] spapr: Improve device tree CPU node for -cpu h

From: Andreas Färber
Subject: [Qemu-ppc] [PATCH v2 3/4] spapr: Improve device tree CPU node for -cpu host with unknown OF name
Date: Fri, 16 Aug 2013 00:35:10 +0200

Whenever DeviceClass::fw_name is not available, derive it from the CPU's
type name, resorting to the parent's type in case of -cpu host, and fill
it in for that class in a PAPR-compliant way with "PowerPC," prefix.
