Tsirkin" , Igor Mammedov , Marcel Apfelbaum , Paolo Bonzini , Richard Henderson , Eduardo Habkost , David Gibson , Markus Armbruster , qemu-ppc@nongnu.org, Pankaj Gupta , Alexander Graf , David Hildenbrand We will need a handful of new functions: - set_addr(): To set the calculated address - get_memory_region(): To add it to the memory region container - get_addr(): If the device has any specific alignment requirements Using these and the existing functions, we can properly assign resources to memory devices.
