Before we boot a remote processor device we often need to map it to
some (specific) bus addresses (e.g. to allow the processor access to
certain peripheral devices), and we're doing it directly with the

Do you think this kind of functionality should be added to the DMA API as well ?

IIRC, it was suggested awhile ago but you supported using the IOMMU
API directly in this case.
