These patches implement softmmu support on unicore32 architecture.
Based on master branch of qemu, the patches can be fetched from:
git://github.com/gxt/QEMU.git unicore32
UniCore32 CPU is embedded in PKUnity-3 SoC, so we add necessary puv3
devices simulation codes together.
Only minimal system control modules are simulated, to make linux kernel
boot and busybox run in initramfs.
Thanks Andreas Farber, Blue Swirl and Chen Weiren for their priceless
advice, which is v4 based on.
Any advice is greatly appreciated.
Thanks,
Guan Xuetao
