Many boards have LEDs which can be used to signal status or alerts.
|
|
U-Boot provides a uclass API to implement this feature. LED drivers
|
|
can provide access to board-specific LEDs. Use of the device tree
|
|
for configuration is encouraged.

depends on ARCH_BMIPS

help
|
|
This option enables support for LEDs connected to the BCM6328
|
|
LED HW controller accessed via MMIO registers.
|
|
HW blinking is supported and up to 24 LEDs can be controlled.
|
|
All LEDs can blink at the same time but the delay is shared, which
|
|
means that if one LED is set to blink at 100ms and then a different
|
|
LED is set to blink at 200ms, both will blink at 200ms.

help

Some drivers can support automatic blinking of LEDs with a given

period, without needing timers or extra code to handle the timing.

This option enables support for this which adds slightly to the

code size.

help
|
|
Turns on led blinking implemented in the software, useful when
|
|
the hardware doesn't support led blinking. Half of the period
|
|
led will be ON and the rest time it will be OFF. Standard
|
|
led commands can be used to configure blinking. Does nothing
|
|
if driver supports hardware blinking.
|
|
WARNING: Blinking may be inaccurate during execution of time
|
|
consuming commands (ex. flash reading). Also it completely
|
|
stops during OS booting.

help
|
|
The LED subsystem adds a small amount of overhead to the image.
|
|
If this is acceptable and you have a need to use LEDs in SPL,
|
|
enable this option. You will need to enable device tree in SPL
|
|
for this to work.
