CONFIG_PCI enables all the pcie host support. Endpoint support should be enabled independent of the host support. Moving pci/endpoint inside pci/Makefile will build endpoint support only if CONFIG_PCI is enabled. For the same reason kept pci/dwc in drivers/Makefile since dwc drivers can be used either in host mode or device mode (or both). Thanks Kishon
