For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED), it may be useful to have some generic stubs (wrapper functions) for the "colored" LEDs. This allows definitions like:
#define GREEN_LED_GPIO 248 /* = PH24 */
#define STATUS_LED_BIT GREEN_LED_GPIO #define STATUS_LED_STATE STATUS_LED_OFF #define STATUS_LED_PERIOD (CONFIG_SYS_HZ / 2)
#define STATUS_LED_GREEN GREEN_LED_GPIO
To keep this optional, it's probably best to introduce an additional configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that. Placing the code in drivers/misc/gpio_led.c also ensures that it automatically depends on CONFIG_GPIO_LED too.
