uClinux hardware registers access

Hi, 

 

I'm using uClinux from nios2-linux-20090730 and I was stuck triying to manage a simple PIO from a device driver, until I noticed that autogenerated nios2.h file does not enable peripheral adresses bit 31 to '1' in order to bypass cache. 

 

Does anyone know the trick to generate a suitable nios2.h with correct no-cache adressess. 

 

thanks
