[PATCH 1/2] PCI: Disable MSI for Freescale PCIe RC mode

2017-09-22 Thread Zhiqiang Hou
From: Hou Zhiqiang The Freescale PCIe controller advertises the MSI/MSI-X capability in both RC and Endpoint mode, but in RC mode it doesn't support MSI/MSI-X by it self, it can only transfer MSI/MSI-X from downstream devices. So add this quirk to prevent use of MSI/MSI-X
