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