# Makefile for building a monitor for the COLDFIRE 5272 eval platform.

# Currently, the only target supported for COLDFIRE platform is EVAL.  When
# the platform count increases to more than 1, the target name should be
# specified on the command line.
#
# NOTE: This port has only been tested running in RAM space of the
# MCF5272 eval board.  It is downloaded using the DBUG command "DL" or "DN".
