IA64 and PARISC uses the same IOMMU hardware but they duplicate the driver for them (the drivers are very similar). Calgary and POWER also have similar IOMMU drivers. But I don't think it's worth merging them.
Unless a new cross-platform IOMMU git tree handles DMA-API changes, there is no point in having such new tree. There is very little non-architecture-specific IOMMU stuff.
