[U-Boot] Problem with disable the datacache
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

Let's go back to the start, please: Which is the original problem you try to solve by disabling the data cache?

Did you read the note about "icache" and "dcache" commands in the README?

I think this request makes little sense - you should fix the original problem instead.
