Yes I was thinking in passing start and end range in iommu_get (because don't need to change rage, it is needed only one time) And create new elements in iommu struct for start and end address or maybe defining the range statically when the structures are Fillup for omapxxx. But I tought I was break other users of iommu Like omap4 and isp and it would be easier to accept an small patch. But I am agree with you it would be better to make it configurable. As tidspbridge iommu migratio seems to be target to 37 I can Make a new patch and resend. Please let me know if you have some suggestions.
