+"""Device tree to C tool
+
+This tool converts a device tree binary file (.dtb) into two C files. The
+indent is to allow a C program to access data from the device tree without
+having to link against libfdt. By putting the data from the device tree into
+C structures, normal C code can be used. This helps to reduce the size of the
+compiled program.
+
+Dtoc produces several output files - see OUTPUT_FILES in dtb_platdata.py
+
+This tool is used in U-Boot to provide device tree data to SPL without
+increasing the code size of SPL. This supports the CONFIG_SPL_OF_PLATDATA
+options. For more information about the use of this options and tool please
+see doc/driver-model/of-plat.rst
