Hi Wolfgang,

These nios2 boards are now supported with the nios2-generic board 
approach, like that of microblaze-generic, instead of adding every nios2 
board to u-boot mainline. The nios2-generic board patch was applied to 
Scott's next branch.

The gpio led can be enabled with the following added to the board config 
file.

/*
  * STATUS LED
  */
#define CONFIG_STATUS_LED        /* Enable status driver */
#define CONFIG_GPIO_LED        /* Enable gpio led driver */

#define STATUS_LED_BIT            2    /* Bit-2 on GPIO */
#define STATUS_LED_STATE        1    /* Blinking */
#define STATUS_LED_PERIOD    (500 / CONFIG_SYS_NIOS_TMRMS) /* 500 msec */

Cheers,
Thomas
