You can't directly access such large memory areas from an AVR, therefore 
it makes no sense to talk about a memory section for it.  You have to 
manually implement some sort of access to the memory (for example, you 
might have the device connected to the standard external memory bus, 
which provides the low address bits, then use paging for the higher bits).
