Optionally treat ck804 memory-mapped PCI configuration space window as a resource. Not enabled by default because the resource should be non-posted and there's no way to express that to the resource allocator.

Can you expand on why the resource should be non-posted? I didn't think non-posted was a requirement of pci config space.
Where are you configuring posted vs non-posted behavior?
Do writes to extended pci config space actually work for you. A coworker hacked something like this together a while ago for one of the boards we support and there is a bug where I can read extended pcie config space but not write to it. Except for a bit of trivial looking I haven't had a chance to dig into that problem.
