It flew out of our all's brain. So best thing would be to post the patches for 
your board and everybody will see if they can help you.

This comment (wd: see include/configs/sequoia.h) should sensitize you:
a) it's disabled on all public 4xx boards. So it's not tested that good as 
other options.
b) you should know would you are doing when you enable it. E.g. USB
will not work with this option and some OS do not like to be loaded
with DCACHE enabled (e.g. OS/9).
