## Name:            Makefile
## Created:         July 2019
## Author(s):       Philip Smart
## Description:     App Makefile - Build an App for the ZPU Test Application (zputa) or the zOS 
##                                 operating system.
##                  This makefile builds an app which is stored on an SD card and called by ZPUTA/zOS
##                  The app is for testing some component where the code is not built into ZPUTA or 
##                  a user application for zOS.

##
## History:         July 2019   - Initial Makefile created for template use.
##                  April 2020  - Added K64F as an additional target and resplit ZPUTA into zOS.
##                  23/4/2020   - Updated to merge mini basic, ed and command processor.
##
## Notes:           Optional component enables:
##                  USELOADB              - The Byte write command is implemented in hw#sw so use it.
##                  USE_BOOT_ROM          - The target is ROM so dont use initialised data.
##                  MINIMUM_FUNTIONALITY  - Minimise functionality to limit code size.
