With this change to qemu and CONFIG_POWER_RESET_SYSCON_POWEROFF=y
enabled in the kernel, the guest will cause qemu to exit when performing
a shutdown. This is useful for detecting the end of a successful CI job.

This is only relevant when passing the device tree to Qemu with the -dtb
option.

It only supports the ast2500 so far.

Excellent !

Can't we find a way to inform Linux that it's running on a "virtual" 
QEMU Aspeed machine ?

I pushed the patches in aspeed-3.1

Thanks,
