Thread-topic: invalidate cache

Hello,
i Wonder if there is any way to invalidate cache for a certain RAM area, I still want to read the ram via the cache since I do not get the speed i need through the PLB buss.
Basically what i want todo is to use ioremap and then invalidate the cache for the mapped memory area to be able to read data which external IP blocks has put in the RAM.

Best Regards 
Nils Hermansson
