The pcie-rcar driver can be built for any ARM platform (for COMPILE_TEST) including those without CONFIG_OF enabled, and that results in a compile-time error: drivers/pci/host/pcie-rcar.c: In function 'rcar_pcie_parse_request_of_pci_ranges': drivers/pci/host/pcie-rcar.c:939:8: error: implicit declaration of function 'of_pci_get_host_bridge_resources' [-Werror=implicit-function-declaration] err = of_pci_get_host_bridge_resources(np, 0, 0xff, &pci->resources, &iobase); In order to allow compile-testing on all platforms, this adds a of_pci_get_host_bridge_resources() helper stub function that gets used when CONFIG_OF_ADDRESS is disabled. This mirrors what we do for other OF-specific functions.
