Does anyone know any links to info on developing device drivers for embedded PPC. I'm having a little trouble understanding the memory managment inside of the drivers, specifically with the CPM. I know most drivers used the Dual port ram to send the data but would it work just as easily with external ram. Would there be any other considerations. The macros which I am confused with are the __va __pa etc... Can I find an explaination of this anywhere.... Thanks
