[yocto] How to properly add new qemu target + testimage support?

[gmane at reliableembeddedsystems.com]

Hi,

I hacked together a qemu target which supports vexpress-a9.

In order to get

core-image-minimal -c testimage

to work as well I had to cook

meta/lib/oeqa/utils/qemurunner.py
scripts/runqemu
scripts/runqemu-internal

This does not seem to be a generic way to do such a thing.

What's the proper way to do it?

Regards,

Robert
