[PATCH 0/5] csky: add shutdown and nolibc support

From: Thomas Weißschuh
Date: Sun Sep 29 2024 - 17:48:07 EST


This series adds support for the C-SKY architecture to nolibc.
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.
