-/*---------------------------------------------------------------------------*/
-/* This header file is the main holder for the declarations and
- * prototypes for the core Angel system. Some Angel concepts are
- * described at the start of this file to ensure that a complete view
- * of the Angel world can be derived purely from the source.

- *     $Date$
- *
- *
- * NOTE: Currently the Angel source is designed to be simple,
- * understandable and easy to port to new hardware platforms. However,
- * this does not always yield the highest performing system. The
- * current layered approach introduces an overhead to the performance
- * of the system. In a true commercial target, this code should be
- * re-designed to build a system where the Angel logical message
- * system, device driver and hardware accesses are merged to provide
- * the best performance.

-/* Angel overview:
-
-... some comments describing Angel ...
-
- * Angel is designed as a kit-of-parts that can be used to provide
- * run-time support for the development of ARM applications. The main
- * core of Angel is in providing support for the "debug" message
- * communication with a host system. These messages do not just cover
- * debugging ARM processes, but also the process of downloading ARM
- * programs or attaching to executing processes on the target.
- *
- * A stand-alone ROM based Angel world is the basic starting point for
- * a system, since it will allow programs to be downloaded to the
- * target. The ROM version of Angel will provide the generic debug
- * support, but no system specific routines. The preferred method of
- * using Angel is as a link library. This ensures that applications
- * carry with them the Angel routines necessary to support debugging
- * (and also ensure that the Angel version is up-to-date, independant
- * of the version in the target ROM). Eventually, once a program has
- * been fully debugged, a ROMmed version of the program can be
- * generated with the Angel code being provided in the application.
-
-.. more comments ..
-
- * The standard Angel routines do *NOT* perform any dynamic memory
- * allocation. To simplify the source, and aid the porting to a non C
- * library world, memory is either pre-allocated (as build-time
- * globals) or actually given to the particular Angel routine by the
- * active run-time. This ensures that the interaction between Angel
- * and the target O/S is minimised.
- *
- * Notes: We sub-include more header files to keep the source
- * modular. Since Angel is a kit-of-parts alternative systems may need
- * to change the prototypes of particular functions, whilst
- * maintaining a fixed external interface. e.g. using the standard
- * DEBUG messages, but with a different communications world.
