[U-Boot-Users] 85xx and flash.c

Hi all, I'm reading the docs and it says that when porting a new board - mine is a custom 8548 - a flash.c is needed. Indeed, most boards have a flash.c but I don't see one for the cds 85xx boards nor the mpc8544ds . I was planning on using CFI for my flash - the spansion S29GL01GP . Do I need a flash.c and if so what reference should I use to get started?

Thanks! Robert
