PciAllocator & mmio_regions ()

Prefetch ranges can be allocated from the general mmio allocator

without any specific restrictions. There's no distinction between

prefetchable and non-prefetchable address space at this point

in the upstream allocation chain. This matters for bridges which

specifically will need their prefetch devices to be within the

prefetch window of upstream bridges.

void PciRoot (uint32_t mbus_id, ddk::PcirootProtocolClient proto)

PciRootAllocators can be trivially constructed because they only need

a way to call protocol operations. We set three of them up for the root

to use for accessing address space over the pciroot protocol.

1) mmio which tries to get mmio addresses

4GB

2) pf_mmio which will allocate anywhere in the mmio space

3) pio which will attempt to allocate from the pio allocator
