| * additional properties: |
| * |
| * 1. On input, it will be '1' if the I/O expansion board is present. |
| * 2. Setting it to an output of '0' will generate a system reset. |
| * 3. Setting it to an output of '1' will not only illuminate the LED |
| * take the card out of reset and enable power to the SD card slot. |
| * |
| * As a consequence, the GREEN LED will not be illuminated if SD card |
| * support or SPI is disabled. The only effect of CONFIG_ARCH_LEDS is that |
| * the GREEN LED will turned off in the event of a crash. |
