Regarding Cyclone FPGA and Top boot Flash memory configuration

hello,

I am trying to use Cyclone FPGA with part no.EP1C20F324 ,with 512 KByte SRAM having part no. IS61WV12816BLL, 2 MByte Flash(top boot Type) having part no. S29AL016D70TAI01X and 4 Mbits EPCS Device. The SRAM is used as working memory,Flash is used to store application code and EPCS is used to store FPGA hardware image.

Can anyone plz guide to use Top boot flash with the NIOS 2 processor.
