Hrm, that's ancient gunk, I'll have to dig. 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 ?
Cheers,
Ben.
