           The minimal simulator HAL package is provided for when only
           a simple simulation of the processor architecture is
           desired, as opposed to detailed simulation of any specific
           board. To use this minimal simulator the command
           `target sim --board=jmr3904pal' should be used from inside
           gdb. It is not possible to use any of the eCos device
           drivers when the simulator is running in this mode"
