allow LED initialization without STATUS_LED_BOOT

2015-10-24T17:50:02+00:00

For current U-Boot to initialize status LEDs via status_led_init(), it
is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined.
This may be a particular concern with GPIO LEDs, where __led_init() is
required to correctly set up the GPIO (gpio_request and
gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't
called, which could leave the user with a non-functional "led" command -
due to the fact that the LED routines in gpio_led.c use gpio_set_value()
just fine, but the GPIO never got set up properly in the first place.

I think having CONFIG_STATUS_LED is sufficient to justify a
corresponding call to status_led_init(), even with no STATUS_LED_BOOT
defined. To do so, common/board_r.c needs call that routine, so it now
is exposed via status_led.h.

cmd_led: Extend led command to support blinking and more leds

2015-04-23T13:43:08+00:00

This patch extends the U-Boot "led" command to support automatic blinking
by setting a blink frequency in milliseconds. Additionally the number of
supported LEDs is increased to 6 (0...5).

This will be used by the PCA9551 LED driver.
