Is it a EPCS device? In that case you program the flash through the FPGA with the JTAG. You add a EPCS Controller Component (either with sopc builder och mega wizard) that which signals you assign to the pins of the flash (data0, dclk, sce and sdo). You can either program the flash with the Flash Programmer GUI in the NIOS 2 IDE (you don't need a nios core for that) or from the nios2 command shell.

I hope this leads you in the right direction
