 * The following parameters are defined here and in the Makefile.

 * Any changes made here must be made in the Makefile and vice versa.
 *
 * ROM_BASE_ADRS is the base of the Flash ROM/EPROM.
 * ROM_TEXT_ADRS is the entry point of the VxWorks image
 * ROM_SIZE is the size of the part of the Flash ROM/EPROM allocated to
 *		the VxWorks image (block size - size of headers)
 *
 * Two other constants are used:
 * 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)
 *
 * The values are given as literals here to make it easier to ensure
 * that they are the same as those in the Makefile.
