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