 *	Memory map
 ********************/

/* Note: - dynamic maps will be mapped using ioremap() with the base addresses and sizes declared in this array (matched to include the requested zones, 
           but not using the actual IxOsalMemoryMap requests) 
         - static maps have to be also declared in arch/arm/mach-ixp425/mm.c using the exact same addresses and size
         - the user-friendly name will be made available in /proc for dynamically allocated maps 
         - the declared order of the maps is important if the maps overlap - when a common zone is requested only the
           first usable map will be always chosen */
