    General notice:
    This code is part of a boot-monitor package developed as a generic base
    platform for embedded system designs.  As such, it is likely to be
    distributed to various projects beyond the control of the original
    author.  Please notify the author of any enhancements made or bugs found
    so that all may benefit from the changes.  In addition, notification back
    to the author will allow the new user to pick up changes that may have
    been made by other users after this version of the code was distributed.

/* Specify inclusion of subsystems within the monitor here.
 * The basic monitor includes the following commands as a minimum:
 *
 * flash, help, reset, setup, version, call (and a few others)
 *
 * Subsystems are included/excluded by defining a few macros to 1/0.
 * Following are the subsystem groupings:
 *
 *  INCLUDE_MEMCMDS:        dm, pm, cm, fm, sm
 *  INCLUDE_PIO:            pio
 *  INCLUDE_EDIT:           edit
 *  INCLUDE_DEBUG:          argv, at, dr, go, pr, ss, vfy, sleep
 *  INCLUDE_DISASSEMBLER:   dis
 *  INCLUDE_UNPACK:         unpack
 *  INCLUDE_ETHERNET:       ether
 *  INCLUDE_TFS:            tfs
 *  INCLUDE_MALLOC:         malloc
 *  INCLUDE_SHELLVAR:       set
 *  INCLUDE_XMODEM:         xmodem
 *
 * Note that these INCLUDE macros allow the monitor to be built in a 
 * variety of configurations; some of which may put extreme limitations
 * on the capability of the monitor.  For example, it is recommended that
 * at least INCLUDE_ETHERNET or INCLUDE_XMODEM be defined otherwise
 * there is no download capability in the monitor.  The INCLUDE_TFS macro
 * is also recommended.
 *
 * An absolute minimum practical configuration should include:
 *      ETHERNET or XMODEM.
 *
 * A minimum configuration that includes typical TFS capabilities should
 * include: TFS, SHELLVAR and {ETHERNET | XMODEM}.
 *
 * NOTICE that for this board (ATLAS) I have just about everything enabled.
 * This is because the monitor is allocated the entire 29F040, so I may as
 * well use the space...
