             Support can be enabled for different varieties of ROM monitor.
323
             This support changes various eCos semantics such as the encoding
324
             of diagnostic output, or the overriding of hardware interrupt
325
             vectors.
326
             Firstly there is \"Generic\" support which prevents the HAL
327
             from overriding the hardware vectors that it does not use, to
328
             instead allow an installed ROM monitor to handle them. This is
329
             the most basic support which is likely to be common to most
330
             implementations of ROM monitor.
331
             \"GDB_stubs\" provides support when GDB stubs are included in
332
             the ROM monitor or boot ROM."
