88 debug software such as Angel or eCos GDB stubs. Select 'rom'
89 when building a stand-alone application which will be put
90 into ROM. Using ROMRAM will allow the program to exist in

253 Support can be enabled for different varieties of ROM monitor.
254 This support changes various eCos semantics such as the encoding
255 of diagnostic output, or the overriding of hardware interrupt
257 Firstly there is \"Generic\" support which prevents the HAL
258 from overriding the hardware vectors that it does not use, to
259 instead allow an installed ROM monitor to handle them. This is
260 the most basic support which is likely to be common to most
261 implementations of ROM monitor.
262 \"GDB_stubs\" provides support when GDB stubs are included in
263 the ROM monitor or boot ROM."
