1280 | help | |
1281 | Enable support for GPIOs (General-purpose Input/Output) in TPL. | |
1282 | GPIOs allow U-Boot to read the state of an input line (high or | |
1283 | low) and set the state of an output line. This can be used to | |
1284 | drive LEDs, control power to various system parts and read user | |
1285 | input. GPIOs can be useful in TPL to enable a 'sign-of-life' LED, | |
1286 | for example. Enable this option to build the drivers in | |
1287 | drivers/gpio as part of an TPL build. | |
