             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."
