      PCI: dwc: Add link up check in dw_child_pcie_ops.map_bus() · 15b23906
      Hou Zhiqiang authored
      NXP Layerscape (ls1028a, ls2088a), dra7xxx and imx6 platforms are either
      programmed or statically configured to forward the error triggered by a
      link-down state (eg no connected endpoint device) on the system bus for
      PCI configuration transactions; these errors are reported as an SError
      at system level, which is fatal.
      
      Enumerating a PCI tree when the PCIe link is down is not sensible
      either, so even if the link-up check is racy (link can go down after
      map_bus() is called) add a link-up check in map_bus() to prevent issuing
      configuration transactions when the link is down.
      
      SError report:
