| 6 | help |
| 7 | Many boards have LEDs which can be used to signal status or alerts. |
| 8 | U-Boot provides a uclass API to implement this feature. LED drivers |
| 9 | can provide access to board-specific LEDs. Use of the device tree |
| 10 | for configuration is encouraged. |

| 15 | help |
| 16 | The LED subsystem adds a small amount of overhead to the image. |
| 17 | If this is acceptable and you have a need to use LEDs in SPL, |
| 18 | enable this option. You will need to enable device tree in SPL |
| 19 | for this to work. |

| 24 | help |
| 25 | Enable support for LEDs which are connected to GPIO lines. These |
| 26 | GPIOs may be on the SoC or some other device which provides GPIOs. |
| 27 | The GPIO driver must used driver model. LEDs are configured using |
| 28 | the device tree. |
