The board gpio.c driver works on Altera PIO component. It will behave exactly the same as the epled driver. I have tested it on EP1C20 an EP2C35 board with standard configuration. I believe it will work with the standard configuration on EP1S10 and EP1S40. I don't want to break anything. It was actually the first gpio driver I wrote for nios2-linux before the custom gpio core.
