Write Back Policy:
Cached data will be written back to SDRAM only when needed.
This can give a nice increase in performance, but beware of
broken drivers that do not properly invalidate/flush their
cache.
Write Through Policy:
Cached data will always be written back to SDRAM when the
cache is updated. This is a completely safe setting, but
performance is worse than Write Back.
If you are unsure of the options and you want to be safe,
then go with Write Through.
