description "
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."
