Took a quick look at the PCI parts, looks like you have a pretty big
DMA restriction.

You could provide your own dma map ops and make the allocator a bit
smarter about where it gets memory (preferentially allocating from the
DMA'able region, which you could hide). Or do you find that swiotlb
does ok in general?

Other than that you had pretty tiny bits of enabling code, I assume
they work on your platform (config space access & setup, etc.).
