- *  Added Brutus LEDs support
- *	Nicolas Pitre, Mar 19, 2000
- *
- *  Added LART LED support
- *      Erik Mouw (J.A.K.Mouw@its.tudelft.nl), April 21, 2000
- *
- *
- *  Assabet uses the LEDs as follows:
- *   - Green - toggles state every 50 timer interrupts
- *   - Red   - on if system is not idle
- *
- *  Brutus uses the LEDs as follows:
- *   - D3 (Green, GPIO9) - toggles state every 50 timer interrupts
- *   - D17 (Red, GPIO20) - on if system is not idle
- *   - D4 (Green, GPIO8) - misc function
- *
- *  LART uses the LED as follows:
- *   - GPIO23 is the LED, on if system is not idle
- *  You can use both CONFIG_LEDS_CPU and CONFIG_LEDS_TIMER at the same
- *  time, but in that case the timer events will still dictate the
- *  pace of the LED.
+ * SA1100 LEDs dispatcher
