*
* based on code from and using (roughly) the same API as the

* Linux Device Driver for Public Domain BDM Interface

/* the interface of the kernel mode driver as of June 10th, 1997
*
* there are a number of ioctl's for all non-speed-critial bdm operations
* these operations allow to reset, restart, stop, step and run the chip,
* to exchange data with the bdm interface, and to set the clocking speed
* and debug-level.
*
* the download of code and the reading back of memory are considered
* speed critical, due to the fact that download times should be minimized
* therefore these two operations are supported by the BDM fill and dump
* commands. these commands are issued automatically by read and write
* system calls on the bdm driver

/* File: bdmops.c (BDM Operations)
* Purpose:
* Author: Rolf Fiedler
* Created:
*
* Initials:
* BCW - Brett Wuth
* @#[ContactWuth:
* Phone: +1 403 627-2460
* E-mail: support@castrov.cuug.ab.ca, wuth@acm.org]
*
* this is an abstraction layer to have a general target programming interface
* so the programmer doesn't have to bother with motorola's bdm commands.
*
* applications only include bdmops.h and call the functions below
*
* HISTORY:
* $Log: bdmops.c,v $
* Revision 1.2 2005/10/24 01:37:25 cjohns
* Fixed includes for building in Windows with MinGW.
*
* Revision 1.1 2003/12/29 22:18:49 codewiz
* Move tools/bdm_abstraction to m68k/bdmabstraction and autoconfiscate.
*
* Revision 1.2 2003/07/04 22:33:01 codewiz
* Applied SST block-erase patch.
*
* Revision 1.1 2003/06/03 15:42:04 codewiz
* Import userland tools from bdm-fiedler
*
* Revision 1.6 2000/09/19 00:28:29 wuth
* cleanly use Fiedler's bdm driver; bdm_mon detects flash errors
*
* Revision 1.5 2000/07/25 13:51:09 wuth
* Working sector erase. Better error reports.
*
* Revision 1.4 2000/04/20 04:56:23 wuth
* GPL. Abstract flash interface.
*
* Revision 1.3 2000/03/28 20:24:41 wuth
* Break out flash code into separate executable. Make run under Chris Johns BDM driver.
*
* Revision 1.2 1999/07/05 22:09:50 wuth
* Abort if can't sync BDM. Work with Am29F800 flash.
* @#[BasedOnTemplate: template.c version 2]
