PCI Passthrough Failing

After updating to the develop-ls-5.15.71-2.2.0 branch in the lx2160a_build repository, I am receiving the following error messages when attempting to bind a PCI device to the vfio-pci driver and then start a VM.

vfio-pci 0001:01:00.0: Unable to change power state from D3hot to D0, device inaccessible

Unknown PCI header type '127'

I am using the same rootfs and kernel as before. Was there something changed in the update from U-Boot 2021.04 to 2022.04 to prevent this passthrough? Or is there something in the patches from the LSDK-21.08 based BSP that I should add to the CEX7 build?

u-boot does some fixups and configurations to the device-tree before booting linux. I would not recommend upgrading one without the other.
