- * (inspired by Kanoj Sarcar's code)
- *
- * Because of the wide memory address space between physical RAM banks on the 
- * SA1100, it's much convenient to use Linux's NUMA support to implement our 
- * memory map representation.  Assuming all memory nodes have equal access 
- * characteristics, we then have generic discontigous memory support.
- *
- * Of course, all this isn't mandatory for SA1100 implementations with only
- * one used memory bank.  For those, simply undefine CONFIG_DISCONTIGMEM.
- *
- * The nodes are matched with the physical memory bank addresses which are 
- * incidentally the same as virtual addresses.
- * 
- * 	node 0:  0xc0000000 - 0xc7ffffff
- * 	node 1:  0xc8000000 - 0xcfffffff
- * 	node 2:  0xd0000000 - 0xd7ffffff
- * 	node 3:  0xd8000000 - 0xdfffffff
