I am not specifically familiar with the SST25VF016. Examine the datasheet and compare it with the datasheet for Altera's EPCS devices:

I'm going to assume that you can probably use the EPCS core. This provides you with a software driver for accessing the flash. If you use the SPI core, you are on your own for the software driver.

Do you have a board already? If it were me, I'd drop in the EPCS controller and just try it.
