104 the system for either RAM bootstrap or ROM bootstrap(s). Select
105 'ram' when building programs to load into RAM using onboard
106 debug software such as Angel or eCos GDB stubs. Select 'rom'
107 when building a stand-alone application which will be put
108 into ROM. Using ROMRAM will allow the program to exist in
109 ROM, but be copied to RAM during startup."

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