+/* LEDs
+ *
+ * The 16z board has 7 LEDs, five of which are controllable via software:
+ *
+ * ----- ------ ------ ------------------------------------
+ * LED Color Signal Description
+ * ----- ------ ------ ------------------------------------
+ * LED1 Red 3V3 Indicates the presence of +3.3V
+ * LED2 Red 5V Indicates the presence of +5V
+
+ * LED3 Blue ~RF Controlled via PH2. Notes: 1, 2
+ * LED4 Green ~SXM Controlled via PH3. Notes: 1, 3
+ * LED5 Green ~SD1 Controlled via PJ0. Notes: 1, 4
+ * LED6 Yellow ~SD2 Controlled via PJ4. Notes: 1, 5
+ * LED7 Yellow ~SD0 Controlled via PJ7. Notes: 1, 6
+ * ----- ------ ------ ------------------------------------
+ *
+ * Note 1: Pulled high so a low output illuminates the LED.
+ * Note 2: PH2/~RF is also used by the RF transceiver, X2. That part is not
+ * populated on my board.
+ * Note 3: ~SXM is the chip select for the serial memory, U4. That part is
+ * not populated on my board.
+ * Note 4: ~SD1 is the chip select for the SD card 1, X11.
+ * Note 5: ~SD2 is the chip select for the SD card 2, X10.
+ * Note 6: ~SD0 is the chip select for the microSD 0, X12.
+ *
+ * In conclusion: None of the LEDs are available to indicate software status
+ * without potentially sacrificing board functionality. If the RF transceiver
+ * is not installed (CONFIG_16Z_RFTRANSCEIVER=n) and if LED support is
+ * requested (CONFIG_ARCH_LEDS), then LED3 will be used to indicate status: A
+ * solid color means that the board has boot successfully; flashing at a rate
+ * of approximately 2Hz indicates a software failure.
