While working on AER support on a ZynqMP based system, which has some
PCIe Device connected via a PCIe switch, problems with AER enabling in
the Device Control registers of all PCIe devices but the Root Port. In
fact, only the Root Port has AER enabled right now. This patch set now
fixes this problem by first fixing the AER enabing in the
interconnected PCIe switches between the Root Port and the PCIe
devices and in a 2nd patch, also enabling AER in the PCIe Endpoints.

Please note that these changes are quite invasie, as with these patches
applied, AER now will be enabled in the Device Control registers of all
available PCIe Endpoints, which currently is not the case.

Stefan Roese (2):
  PCI/portdrv: Don't disable AER reporting in
    get_port_device_capability()
  PCI/AER: Enable AER on Endpoints as well
