These patches implement softmmu support on unicore32 architecture.
UniCore32 CPU is embedded in PKUnity-3 SoC, so we add hw/pkunity dir
to contain all puv3 devices simulation codes together.
Only minimal system control modules are simulated, to make linux kernel
boot and busybox run in initramfs.
Any advice is greatly appreciated.
Thanks,
Guan Xuetao
