- Adding support for versal CPM as Root port.
- The Versal ACAP devices include CCIX-PCIe Module (CPM). The integrated
  block for CPM along with the integrated bridge can function
  as PCIe Root Port.
- Versal CPM uses GICv3 ITS feature for assigning MSI/MSI-X
  vectors and handling MSI/MSI-X interrupts.
- Bridge error and legacy interrupts in versal CPM are handled using
  versal CPM specific MISC interrupt line.
