Falkor's prefetch tuning structure still carries the L2 cache size value from
early support code. This patch updates it to match the specifications.
Even though the prefetcher is currently disabled for Falkor, we have a patch
waiting for GCC development to reopen that re-enables it, so i take it this
update should be trivial enough to go in before development reopens?
Thanks,
Luis
