/*
 * The blue front LED is wired to the CPLD and can blink in relation with the
 * SATA activity.
 *
 * The following array detail the different LED registers and the combination
 * of their possible values:
 *
 * led_off   | blink_ctrl | SATA active | LED state
 *           |            |             |
 *    1      |     x      |      x      |  off
 *    0      |     0      |      0      |  off
 *    0      |     1      |      0      |  blink (rate 300ms)
 *    0      |     x      |      1      |  on
 *
 * Notes: The blue and the red front LED's can't be on at the same time.
 *        Red LED have priority.
