Can we select IOMMU_DMA under IOMMU_SUPPORT instead? The only drivers not using IOMMU_DMA are the arm32 ones, afaics. If we could get rid of the arm32 exception, the IOMMU_DMA symbol could also go away entirely and we handle it under IOMMU_SUPPORT instead. But that is something for the future :) Regards, Joerg
