agl-kvm-demo-platform: Add recipe
Add agl-kvm-demo-platform image recipe. If "agl-kvm" has been given to aglsetup.sh, it can be built to generate a minimal host image that runs IVI and cluster images with QEMU+KVM. The guest images are built with the "agl-guest-kvm" that the "agl-kvm" feature enables, and are built against the virtio-aarch64 target. The guest images to build can be overriden with the variables GUEST_VM1_IMAGE and GUEST_VM2_IMAGE (from e.g. site.conf). At present this image has only been tested on the AGL reference platform, and development is likely required to get it working on other platforms. COMPATIBLE_MACHINE has not been set in the recipe to ease experimenting, that may change. Known issues: - Currently graphics output from the guests is corrupted when they first boot, and a manual reboot is required of each guest. - Peripheral support is still a WIP. Audio has been configured, but needs further debugging. CAN, USB, etc., are to follow.
