Support can be enabled for four 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.
Next there is \"SLoad\" support which configures eCos to assume it
will be downloaded into RAM via a ROM monitor using S-records.
\"CygMon\" provides support for the Cygnus ROM Monitor.
And finally, \"GDB_stubs\" provides support when GDB stubs are
included in the ROM monitor or boot ROM."
