/* 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.
*
* $Revision$
* $Date$
*
*
* 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.

* Algorithm: We need to present the data in a form that all boards can
* swallow. With the PID board, this is a problem: for reasons
* described in the driver (angel/pid/st16c552.c), data are
* sent a nybble at a time on D0-D2 and D4; D3 is wired to ACK,
* which generates an interrupt when it goes low. This routine
* fills in an array of nybbles, with ACK clear in all but the
* last one. If, for whatever reason, the write fails, then
* ACK is forced high (thereby enabling the next write a chance
* to be noticed when the falling edge of ACK generates an
* interrupt (hopefully).
*
* Params:
* Input: txstate Contains the packet to be sent
*
* Returns: Number of *complete* bytes written

* Angel C Libary support channel protocol definitions
*
* $Revision$
* $Date$
*
*
*
*
* MESSAGE FORMAT
* --------------
* Format of the "data" section of C Lib Support Channel Messages.
* You will notice that the format is much the same as the format
* of ADP messages - this is so that multi-threaded C Libraries can
* be supported.
*
* unsigned32 reason - Main C Library reason code.
* unsigned32 debugID - Info. describing host debug world;
* private to host and used in any target
* initiated messages.
* unsigned32 OSinfo1 \ Target OS information to identify process/thread
* unsigned32 OSinfo2 / world, etc. These two fields are target defined.
* byte args[n] - Data for message "reason" code.
*
* The "debugID" is defined by the host-end of the protocol, and is used
* by the host to ensure that messages are routed to the correct handler
* program/veneer (eg. imagine several threads having opened stdout and
* each writing to a different window in a windowed debugger).
*
* NOTE: The reason that there is no "size" information, is that the
* message IDs themselves encode the format of any arguments.
*
* For further discussion of the format see adp.h
*
* N.B. All streams are little endian.
*
* CLIB REASON CODE
* ----------------
* The message reason codes contain some information that ties them to
* the channel and direction that the message will be used with. This
* will ensure that even if the message "#define name" is not
* completely descriptive, the message reason code is.
*
* b31 = direction. 0=Host-to-Target; 1=Target-to-Host;
* b30-16 = reserved. should be zero
* b15-0 = message reason code.
*
* Note that typically a request will be initiated by the target side, and
* that the host will then respond with either an acknowledgement or some
* data. In either case the same reason code will be used, but the direction
* bit will be reveresed.
