No, the iommu type is SPAPR_TCE, but the *window* info you get here is
the 32-bit window. My thinking is add some versionning and a bunch of
reserved fields to that info struct so we can stick a few more things,
or at the very least add a flags field, so we can return if/when we
support DDW etc... on that iommu.

Cheers,
Ben.
