        description   "
           When targetting the CME555 board it is possible to build
           the system for either RAM bootstrap or ROM bootstrap. RAM
           bootstrap requires that the MPC555 internal flash contains a
           suitable ROM monitor or equivalent software that allows GDB 
           to download the eCos application on to the board. The ROM 
           bootstrap requires that the eCos application be blown into 
           the MPC555 internal flash array. Both types of startup require
           the internal flash array to be enabled. Both startup types expect
           the boards RAM to be present on CS0 and the external flash on
           CS1. CS2 is not used by eCos and can e.g. be used for memory
           mapped I/O by your application. Typical use of the board could be
           to build GDB-stubs for ROM bootstrap, use AXIOM's monitor to 
           program it in internal flash, and then change the necessary 
           switches and jumpers to enable internal flash and get the memory 
           map right. Consult the CME555 manual to make sure you have all
           jumper settings correct."
