# This function changes the default tune for machines which
# are based on armv7a or armv7ve to use common tune value, note
# that we enforce hard-float which is default on Linux microPlatform.
# If you have one of those machines which are armv7a or armv7ve but
# can't support hard-float, please change tune = 'armv7athf' to
# tune = 'armv7at' below but then this is for your own distro.
