| 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. | |

| 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. | |

| 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. | |

| 33 | help | |
| 34 | This option is an SPL-variant of the LED_GPIO option. | |
| 35 | See the help of LED_GPIO for details. | |
