           The JMR3904 HAL package should be used when targetting the
           actual hardware. The same package can also be used when
           running on the full simulator, since this provides an
           accurate simulation of the hardware including I/O devices.
           To use the simulator in this mode the command
           `target sim --board=jmr3904' should be used from inside gdb."

           When targetting the JMR3904 board it is possible to build
           the system for either RAM bootstrap or ROM bootstrap. The
           former generally requires that the board is equipped with
           ROMs containing the Cygmon ROM monitor or equivalent
           software that allows gdb to download the eCos application
           on to the board. The latter typically requires that the
           eCos application be blown into EPROMs or equivalent
           technology."
