In other words, don't you need something more like: > > #ifdef CONFIG_SPL_BUILD > tegra_spl_gpio_direction_output(GPIO_PI4, 1); > #else > gpio_request(GPIO_PI4, NULL); > gpio_direction_output(GPIO_PI4, 1); > #endif Sadly not, at this point the gpio driver isn't available yet, that's why one need to use tegra_spl_gpio_direction_output(). As mentioned in the commit log I copied this from seaboard, assuming it would be correct. AFAICT the gpio_request() could be removed too, it doesn't work at this point anyway. > ... although perhaps the SPL and non-SPL code should simply be separated > into separate files, so that there's no need for ifdefs, and it's > obvious if SPL and non-SPL code are duplicating the same work? Actually none of the code from tamonten.c is needed for the SPL, a build with both function under #ifndef CONFIG_SPL_BUILD works just fine. Any pointer on how I can get tamonten.c out of the SPL build? Alban
