[PATCH v2] pci/probe: Enable CRS for root port if it is supported

2014-09-02 Thread Rajat Jain
As per the PCIe spec, an endpoint may return the configuration cycles with CRS if it is not yet fully ready to be accessed. If the CRS visibility is not enabled at the root port, the spec leaves the retry behaviour open to implementation in such a case. The Intel root ports have chosen to retry en
