I think it's a de facto standard that type 12 means "nvdimm". I don't
think there's any kind of standard as to whether that means that it's
permissible to touch that memory or that nvdimm means type 12.

I have no problem w/ the resource name saying "nvdimm", but I do
object to autoloading anything as a result.

(There is no type 12 on EFI, nor will there ever be, since there is no
e820 at all on EFI.)
