Cleaning cache on a SBC2440-II (ARM920T) board

["Malte Wienecke" <Malte.Wienecke@xxxxxx>]

Hi,

Is there a possibility to clean the data cache on an arm920t board  
under arm-linux?

I'm working on a c program, where a lookup table must be removed from  
the cache or the entire cache cleaned.
Is this possible without causing an segmentation fault as normal root  
user?

I read that with following code it is possible to clean and invalidate  
the dcahe:
MCR p15,0,Rd,c7,c14,1
How can I add this to my programm with inline assembler?

Thanks!
