Loongarch virt machine uses general hardware reduces acpi method, rather than LS7A acpi device. Now only power management function is used in acpi ged device, memory hotplug will be added later. Also acpi tables such as RSDP/RSDT/FADT etc. The acpi table has submited to acpi spec, and will release soon.
