FPGA to FLASH and back?

Hi,



I'd like to use an Intel StrataFlash Memory 28F320J3A with my Virtex4 FPGA

and write / read data from it. Is there a ready-to-use core available to 
communicate with the Flash or am I supposed to start from the scratch, 
writing VHDL code line by line.



Does anybody know how complicated this can get? Is it something 
sophisticated or just "line production"..?! ;-)
