	  Adds support for the Intel Volume Management Device (CONFIG_VMD). CONFIG_VMD is a
	  secondary CONFIG_PCI host bridge that allows CONFIG_PCI Express root ports,
	  and devices attached to them, to be removed from the default
	  CONFIG_PCI domain and placed within the CONFIG_VMD domain. This provides
	  more bus resources than are otherwise possible with a
	  single domain. If you know your system provides one of these and
	  has devices attached to it, say Y; if you are not sure, say N.
