It is hard to find a usable C-SKY userspace and compiler, so having support in nolibc provides an easy way to perform tests there. The nolibc test suite requires system power off support in QEMU, so a driver for that is added, too. I'm not sure who is responsible for drivers/virt/ and can take the driver.
