/*

 * Like the SA1100, the EDB7211 has a large gap between physical RAM

 * banks.  In 2.2, the Psion (CL-PS7110) port added custom support for

 * discontiguous physical memory.  In 2.4, we can use the standard

 * Linux NUMA support.

 *

 * This is not necessary for EP7211 implementations with only one used

 * memory bank.  For those systems, simply undefine CONFIG_DISCONTIGMEM.

 */

/*

 * The PS7211 allows up to 256MB max per DRAM bank, but the EDB7211

 * uses only one of the two banks (bank #1).  However, even within

 * them, so we use 24 for the node max shift to get 16MB node sizes.

 */

/*

 * 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 

 * characteristics, we then have generic discontiguous 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
