This is intended to be used with LEDE project to provide image for use with
QEMU ARM virt machine.

Run with qemu-system-arm

        # boot with initramfs embedded in
        qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage-initramfs

        # boot with accel=kvm
        qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
        openwrt-armvirt-32-zImage-initramfs

        # boot with a separate rootfs
        qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage \
          -drive file=openwrt-armvirt-32-root.ext4,format=raw,if=virtio -append 'root=/dev/vda rootwait'

        # boot with local dir as rootfs
        qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage \
          -fsdev local,id=rootdev,path=root-armvirt/,security_model=none \
          -device virtio-9p-pci,fsdev=rootdev,mount_tag=/dev/root \
          -append 'rootflags=trans=virtio,version=9p2000.L,cache=loose rootfstype=9p'

Run with kvmtool

        # start a named machine
        lkvm run -k openwrt-armvirt-32-zImage -i openwrt-armvirt-32-rootfs.cpio --name armvirt0

        # start with virtio-9p rootfs
        lkvm run -k openwrt-armvirt-32-zImage -d root-armvirt/

        # stop "armvirt0"
        lkvm stop --name armvirt0

        # stop all
        lkvm stop --all

The multi-platform ARMv8 target can be used with QEMU:

        qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
                -kernel openwrt-armvirt-64-Image-initramfs \
