P4080: 36bit address: How to use these address space beyond 4GB?

[carlpeng]

As we know, P4080 is E500MC core, it is a 32 bit CPU core. But at meanwhile, P4080 support 36bit address.

So, my questions is how to use these address space beyond 4G(since 32 bit CPU only can initiate at most 4G address)?

Could you please share some doc with me? Thanks a lot!
