Ok, I take a look at these function an see: 

void alt_sys_init( void )
{
    ALTERA_AVALON_TIMER_INIT ( TIMER_STAMP, timer_stamp);
    ALTERA_AVALON_TIMER_INIT ( TIMER_US, timer_us);
    ALTERA_AVALON_TIMER_INIT ( WATCHDOG, watchdog);
    ALTERA_AVALON_EPCS_FLASH_CONTROLLER_INIT ( EPCS_FLASH_CONTROLLER, epcs_flash_controller);
    ALTERA_AVALON_JTAG_UART_INIT ( JTAG_UART_0, jtag_uart_0);
    ALTERA_AVALON_SPI_INIT ( SPI_ADC, spi_adc);
    ALTERA_AVALON_SPI_INIT ( SPI_DAC, spi_dac);
    ALTERA_AVALON_SYSID_QSYS_INIT ( SYSID, sysid);
    ALTERA_AVALON_UART_INIT ( DEBUG_UART, debug_uart);
}

So it is present.

Now I look in altera_avalon_epcs_flash_controller.h and see: 

#define ALTERA_AVALON_EPCS_FLASH_CONTROLLER_INIT(name, dev) 
alt_epcs_flash_init(&dev)

So it is not empty.

As already said, I use the small driver option, but I define ALT_USE_EPCS_FLASH.

Any ideas? Or did I miss something?
