            Support can be enabled for three different varieties of ROM monitor.
            This support changes various eCos semantics such as the encoding
            of diagnostic output, or the overriding of hardware interrupt
            vectors.
            Firstly there is \"Generic\" support which prevents the HAL
            from overriding the hardware vectors that it does not use, to
            instead allow an installed ROM monitor to handle them. This is
            the most basic support which is likely to be common to most
            implementations of ROM monitor.
            \"GDB_stubs\" provides support when GDB stubs are included in
            the ROM monitor or boot ROM."
