// Name: mtest.c
// Created: July 2019
// Author(s): Philip Smart
// Description: Standalone App for the zOS/ZPU test application.
// This program implements a loadable appliation which can be loaded from SD card by
// the zOS/ZPUTA application. The idea is that commands or programs can be stored on the
// SD card and executed by zOS/ZPUTA just like an OS such as Linux. The primary purpose
// is to be able to minimise the size of zOS/ZPUTA for applications where minimal ram is
// available.
//
// Credits:
// Copyright: (c) 2019-2020 Philip Smart <philip.smart@net2net.org>
//
// History: July 2019 - Initial framework creation.
// April 2020 - Updates to function with the K64F processor and zOS.
//
// Notes: See Makefile to enable/disable conditional components
