Help text

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.
