If I want to put software program elf file into flash, do I need a flash controller?

If I want to put software program elf file into flash, then the system can load program automatically after power on, I think I need to add a flash controller in my qsys system, correct? Is Altera Avalon Flash the right IP I should use/

Thanks.

    Altera supplies some libraries for writing the epcs/epcq devices from software if the avalon epcs controller IP is instantiated. One way to discover the correct elf offset is to run elf2flash with the --after option.
