We potentially can support ISA devices DMA'ing from an ISA bridge... but via the iommu, which means isa_virt_to_bus is a non-starter. But then, do we really care ? IE. Is there single device that actually requires ISA_DMA_API and that is expected to work on any currently supported powerpc hw ? :-) We don't even support PReP anymore, so that leaves us with what ? Anybody has an objection to turning ISA_DMA_API off ?
