 * ROM_BASE_ADRS is the base of the Flash ROM/EPROM.

 * ROM_SIZE is the size of the part of the Flash ROM/EPROM allocated to

 * ROM_COPY_SIZE is the size of the part of the ROM to be copied into RAM
 * 		 (e.g. in uncompressed boot ROM)
 * ROM_SIZE_TOTAL is the size of the entire Flash ROM (used in sysPhysMemDesc)
