bool "Enable LED support"
depends on DM
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.
bool "Enable LED support in SPL"
depends on LED
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.
