# 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/mbedtls_config.h
|
|
# thread configs/config-thread.h
|
|
# suite-b configs/config-suite-b.h
|
|
# psk configs/config-ccm-psk-tls1_2.h
