IBM 440GP 36-bit addressing

Hi,

I am new to PPC Linux. I am working on IBM 440 GP board. I am using
MontaVista Linux source code. I didn't understand how 36-bit addressing is
taken care in this code. If an application has to access the a memory
location in SDRAM of 440 GP or its internal peripheral registers, whether it
has to pass 36-bit address or normal 32-bit address.

I am afraid my doubt is silly one. But still I am totally confused.

Hope to get reply soon.

Thanks and regards,
Vishwanath
