With the 3 private slots, this gives us 512 slots total. Motivation for this is in addition to assigned devices support more memory hotplug slots, where 1 slot is used by a hotplugged memory stick. It will allow to support upto 256 hotplug memory slots and leave 253 slots for assigned devices and other devices that use them.
