[U-Boot-Users] How to set CPU speed to 266mhz s3c2410?

Sorry for the newb question but I've been googling like mad and can't find any clues (or more likely, can't understand what I do find).

I'm looking at speed.c under /cpu/arm920t/s3c24xx and thinking this is the business end of CPU speed setting. I've been greping the source to see if I can track back to something calling them that I can understand, but no luck.

Any kind soul out there able to tell me how?
