Primary problems I see with your patches:
1. They are not split enough. Still the patch 2/3 is dependent on 3/3. That mean, it would break the compilation. There is no simpler way to solve this except breaking the patch into multiple patches and slowly introducing each function/feature.
 (One obvious way would be to have 3/3 as 2/3 and vice-versa - Not sure what that blocks).

2. Documentation - there is none right now. Being a special use case for PCI, I think a lot of people would benefit if you can explain the comments about why iFPGA bus is required through documentation.

3. Meson as requested by Bruce. Problem you will face is that rawdev doesn't yet have meson enabled. I will work on that. If you can still rework your patches for (1)+(2), I think meson enable over rawdev would be trivial.

Other issues being license plate in opae code not being SPDX. But, I will leave that you and maintainers to decice.
