 # Create a JSON file based on factory data given via kConfigs.
 #
 # This function creates a list of arguments for external script and then run it to write a JSON file.
 # Created JSON file can be checked using JSON SCHEMA file if it is provided.
 #
 # This script can be manipulated using following kConfigs:
 # - To merge generated factory data with final zephyr.hex file set kConfig CONFIG_CHIP_FACTORY_DATA_MERGE_WITH_FIRMWARE=y
 # - To use default certification paths set CONFIG_CHIP_FACTORY_DATA_USE_DEFAULTS_CERTS_PATH=y
 #
 # During generation process a some file will be created in zephyr's build directory:
 # - <factory_data_target>.json a file containing all factory data written in JSON format.
 #
 # [Args]:
 #   factory_data_target - a name for target to generate factory_data.
 #   script_path         - a path to script that makes a JSON factory data file from given arguments.
 #   schema_path         - a path to JSON schema file which can be used to verify generated factory data JSON file.
 #                         This argument is optional, if you don't want to verify the JSON file put it empty "".
 #   output_path         - a path to output directory, where created JSON file will be stored.
