Note that there still seem to be issues with liblitepcie as litepcie_util can't open the device even though the device shows up properly now, even though dmesg can read out the version. Will investigate further tomorrow.

Looks like that just needed a reboot. That leaves only the DMA side by the looks of it. Signing off

Seems to have minor issues still, and is not tuned yet for speed. Verifying the further changes I made still to confirm it doesn't touch anything untowardly w/ non gen4 xcau devices
