ok.  since kernel/setup.c does:

static int __init customize_machine(void)
{
        /*
         * customizes platform devices, or adds new ones
         * On DT based machines, we fall back to populating the
         * machine from the device tree, if no callback is provided,
         * otherwise we would always need an init_machine callback.
         */
        if (machine_desc->init_machine)
                machine_desc->init_machine();
#ifdef CONFIG_OF
        else
                of_platform_populate(NULL, of_default_bus_match_table,
                                        NULL, NULL);
#endif
        return 0;
}
