[ixp1200] Prefetch and Non-Prefetch SDRAM

Hi, Could someone tell me the distinction between prefetch and non-prefetch SDRAM on the IXP1200? And why does the resource manager provided with the IXA Ace framework use only the uncached SDRAM? While at it could someone tell me what is the cache flush area meant to be? Thanks! Shyamal Pandya.
