Here adds test support for little endian 64-bit PowerPC. The powernv machine of qemu-system-ppc64le is used for there is just a working powernv_defconfig. As the document [1] shows: PowerNV (as Non-Virtualized) is the “bare metal” platform using the OPAL firmware. It runs Linux on IBM and OpenPOWER systems and it can be used as an hypervisor OS, running KVM guests, or simply as a host OS.
