help
|
|
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.

|
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.

Enable support for LEDs which are connected to GPIO lines. These

GPIOs may be on the SoC or some other device which provides GPIOs.
