Another way multiple virtio-mmio devices should be added like other arches. And there should be fdt/acpi table added for the device so that users can use it.

Add virtio-mmio bus support for LoongArch, so that devices could be added in the virtio-mmio bus. Signed-off-by: Tianrui Zhao <zhaotianrui@loongson.cn> --- hw/loongarch/Kconfig | 1 + hw/loongarch/virt.c | 3 +++ 2 files changed, 4 insertions(+)
