Process involved in loading POF file from flash

The loader function would not load the file into the fpga, that is just used to load the file into the flash device from the FPGA.

Regarding your answer, what is the easiest/cheapest way to implement that and are there good example projects or is it as simple as writing a driver for an LCD. For example, all that is needed is code that tells the flash to write to the FPGA configure pins for x amount of address locations and then wait for the config done pin to tell it everything went smooth otherwise rewrite?
