# Purpose
#
# This script determines ROM size (or code size) for the standard mbed TLS
# configurations, when built for a Cortex M3/M4 target.
#
# Configurations included:
# default include/mbedtls/config.h
# thread configs/config-thread.h
# suite-b configs/config-suite-b.h
# psk configs/config-ccm-psk-tls1_2.h
#
# Usage: footprint.sh
