- 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 interrupt line. Changes for v8: - Added support for handling error events and INTx interrupts separately using nested chained irqchips. - Added support to free allocated resources in error cases.
