Assuming you have the pinout right and your design meets timing this is all you need to program the flash using the Nios II flash programmer:

Nios II with level 1 debug

Flash controller

Onchip RAM with the exception and reset vectors for the Nios II processor pointing at it

System ID (optional but always a good idea to have in your design)

The flash programmer sends the data to the debug module then Nios II writes the data to the flash. So there isn't much hardware needed to do this.
