You have to do so.
That will prevent CPU from fetching data or instructions from i-cache and
d-cache
at the initialization time since the cache is not initialized yet.

Hi,
I found in mpc85xx start.s, before doing any initialization it disabled
i-cache & d-cache. Must we do so? If we don't disable them what will it
cause?
Best Regards
Enorm
