Address space of an SoC using A2I core #52

Hi, I am curious about the memory address space of an SoC such as Blue Gene/Q using the A2I core. Besides this, I also tried to search the address space of the powerPC and power-series server but also did not find any useful information. Any recommended references?

What do you mean by 'address space'? Do you mean address translation, or how software uses the memory space?

I mean in Power servers, which memory space is assigned to DDR and which memory space is assigned to I/O devices. For example, 0 - 2GB is assigned to I/O, 2GB-4GB is assigned to DRAM, 4GB-16GB is reserved and 16GB-32 GB is assigned to I/O and so on. Any public references?
