[Qemu-devel] [PATCH v2 06/17] spapr: route all memory devices through the machine hotplug handler

[David Hildenbrand]

Necessary to hotplug them cleanly later. We can only support memory
devices that are not DIMMs if we have a parent bus. Otherwise we might
miss "Device '%s' can not be hotplugged on this machine" cases.
