Also, the point of using platform data was to add it to omap3_devices in omap-iommu.c, see[1]. I thought the platform data start/end would move to struct iommu, and iommu_set_da_range would change the start/end on struct iommu, but that would only be necessary if the platform data doesn't match that. If there's no sensible platform data default, then there's no point in using platform data, as the platform is not the limiting factor, but the DSP SW.
