 * Boot ROM is an image written into Flash ROM and started

 *
 * The following parameters are defined here and in the Makefile.
 * They must be kept synchronized; effectively config.h depends on
 * Makefile. Any changes made here must be made in the Makefile and vice
 * versa.
 *
 * ROM_BASE_ADRS is the base of the Flash ROM
 * ROM_TEXT_ADRS is the entry point of the VxWorks image
 * ROM_SIZE is the size of the part of the Flash ROM allocated to the VxWorks
 *          image (block size - size of headers - NVRAM allocation)
 *
 * Two other constants are used:
 * ROM_COPY_SIZE is the size of the part of the ROM to be copied into RAM
