+Processes NXP iMX.RT signal configuration files

+Given a processor folder, generates the SOC level gpio DTSI mux options used
+within Zephyr. These definitions should be copied where appropriate.
+
+This tool is intended to be used with the configuration data downloaded
+from NXP's website. One way to extract this config data is to use the
+MCUXpresso configuration tool to download processor defintions, locate
+those defintions on the disk. Alternatively, individual processor config
+data packs can be downloaded from the MCUXpresso SDK builder tool. Either way,
+the path to the 'processors' directory must be provided as the 'cfg-tool-root'
+parameter.
