13 * Because of the wide memory address space between physical RAM banks on the
14 * SA1100, it's much convenient to use Linux's SparseMEM support to implement
15 * our memory map representation.  Assuming all memory nodes have equal access
16 * characteristics, we then have generic discontiguous memory support.
17 *
18 * The sparsemem banks are matched with the physical memory bank addresses
19 * which are incidentally the same as virtual addresses.
