 * The blue front LED is wired to the CPLD and can blink in relation with the

 * SATA activity. This feature is disabled to make this LED compatible with

 * the leds-gpio driver: MPP14 and MPP15 are configured to act like output

 * GPIO's and have to stay in an active state. This is needed to set the blue

 * LED in a "fix on" state regardless of the SATA activity.
