             Support can be enabled for different varieties of ROM monitor.

             This support changes various eCos semantics such as the encoding

             of diagnostic output, or the overriding of hardware interrupt

             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."
