[PATCH v2 1/2] PCI: iproc: Add CRS check in config read

2019-02-04 Thread Srinath Mannam
In the current implementation, config read output data 0x0001 is assumed as CRS completion. But sometimes 0x0001 can be a valid data. IPROC PCIe host controller has a register to show config read request status flags like SC, UR, CRS and CA. So that extra check is added to confirm the CRS
