| 9 | Enable support for GPIOs (General-purpose Input/Output) in U-Boot. |
| 10 | GPIOs allow U-Boot to read the state of an input line (high or |
| 11 | low) and set the state of an output line. This can be used to |
| 12 | drive LEDs, control power to various system parts and read user |
| 13 | input. GPIOs can be useful to enable a 'sign-of-life' LED, |
| 14 | for example. Enable this option to build the drivers in |
| 15 | drivers/gpio as part of an U-Boot build. |
