Any chance I can get a new test kernel without PCIe quirks? I just got a much more recent image from jnettlet with the following comments:

If you are using that recent uefi firmware I posted then you shouldn't be using the quirks for pcie.  That has an ecam shift setup where it should behave....relatively to SBSA standards.
it definitely won't work with the quirk enabled though.  I have to add an interface to edk2 to turn the mode on or off depending if you want access to the root bus and have a kernel with the quirk applied, or you want it to work with just the devices exposed but in a more compliant manner without quirks
