# Downloads necessary to build with OPTIMIZED_KERNEL_DIR=xtensa.
#
# Called with four arguments:
# 1 - Path to the downloads folder which is typically
# tensorflow/lite/micro/tools/make/downloads
# 2 - Xtensa variant to download for (e.g. hifi4)
#
# This script is called from the Makefile and uses the following convention to
# enable determination of sucess/failure:
#
# - If the script is successful, the only output on stdout should be SUCCESS.
# The makefile checks for this particular string.
#
# - Any string on stdout that is not SUCCESS will be shown in the makefile as
# the cause for the script to have failed.
#
# - Any other informational prints should be on stderr.
