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