We have been through this before, several times. Many times actually.
I have explained it to you, and so did others.

It is perfectly fine with me if you ignore my advice. But then please
stop posting the same question again and again here.

You will not receive any new answers.

Again, and definitely for the last time:

It makes no sense to try to enable the data cache on a MPC82xx system
in U-Boot; the time you could save if you succeeded  is  marginal  to
your application startup time.

And in Linux the D-Cache is enabled, so no changes are needed.
