NXP arm aer interrupt was not MSI/MSI-X/INTx but using interrupt line independently. This patch add a "aer" interrupt-names for aer interrupt. With the interrupt-names "aer", code could probe aer interrupt line for pcie root port, replace the aer interrupt service irq. This patch is intend to fixup the Layerscape platforms which aer interrupt was not MSI/MSI-X/INTx, but using interrupt line independently.
