+         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.
