If you are going to use passive serial mode, you can use any type of flash memory you want to. The idea here would be that the uController programs the FPGA.

The full details of how to configure the FPGA in passive serial mode are found in the user's guide for the Cyclone III. Specifically:

Configuration involves controlling the nConfig, DCLK, and at least DATA0 lines. In addition, you monitor at least the nStatus line.
