iommu: dma-mapping-fast: Avoid pci memory regions Certain memory regions are reserved by pci devices. When an endpoint makes an access to these regions, the access is routed to the appropriate location with the pci complex, and does not pass through the iommu into the greater system. Therefore these address cannot be used for dma. Change-Id: I1e909e4c0fbcadd53576b27a57cc49ed131cf328 Signed-off-by: Patrick Daly <pdaly@codeaurora.org>
