 * led adresses and blinker code
 *
 * this file is part of the chdk project

 * GPL v3+
 *
 * creates for each LED 3 functions (e.g. green):
 *
 * 1. blink_LED_GREEN()
 * 2. LED_GREEN_ON()
 *    LED_GREEN_OFF()
 *
 * can also used from asm: BL LED_GREEN_ON
 *
 * to 1.
 * saves and restores registers on stack.
 * Be careful when using from Supervisor mode,
 * (that means while booting!)
 * it may crash while interrupts are active
 *
 * to 2.
 * register r2 and r3 are clobbered !
