* Because of the wide memory address space between physical RAM banks on the
* SA1100, it's much more convenient to use Linux's NUMA support to implement
* our memory map representation. Assuming all memory nodes have equal access

* Of course, all this isn't mandatory for SA1100 implementations with only

* The nodes are matched with the physical memory bank addresses which are
