           The JMR3904 HAL package should be used when targetting the

           accurate simulation of the hardware including I/O devices.

           `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
