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