Add a trivial dom0less test: - build Linux defconfig arm64 to be used as dom0/U kernel - use busybox-static to create a trivial dom0/U ramdisk - use ImageBuilder to generate the uboot boot script automatically - install and use u-boot from the Debian package to start the test - binaries are loaded from uboot via tftp Disabling the pl061 device is required to get any version of Linux to boot on Xen on qemu-system-aarch64.
