        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."
