Hi all,

I have a question about cache activation on the Xilinx Virtex4 ML403 board.

I know that PowerPC instruction and data caches have to be activated
manually with the command 

XCache_EnableICache(); 

XCache_EnableDCache();

It works well with the standalone application, but how about it in Linux
system?

 When porting a linux 2.6 on the board, how the  cache can be activated by
the OS?

Thanks
