The right approach -- assuming you reach an agreement with Peter -- is to revert commist c2f24ba3218a and 8c8f886f2755 first (in this order), then remove the PcdPciDisableBusEnumeration setting from the DSC altogether (given the DEC default of the PCD being FALSE). Independently, please use "python3 $EDK_TOOLS_PATH/Scripts/GetMaintainer.py", for determining the propert set of CC's for every patch in a series. I have no comments on the other patches (especially the 4th one), as they are tied to bhyve platform internals, which I'm unfamiliar with.
