[U-Boot] Problem with disable the datacache

[Lasse Skov]

Hi 

I have a problem with disabling the data cache on my PPC.
The target family is mpc83xx and i had tried to chance
something in the start.S file for the ppc.
But if i instead of the asm function dcache_enable use dcache_disable
my target newer get running.
So if anyone can help with informations about how to disable the data cache
for a ppc it could be greath.

Kind Regards
LSkov
