"""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 two output files:
dt-structs.h - contains struct definitions
dt-platdata.c - contains data from the device tree using the struct
definitions, as well as U-Boot driver definitions.
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.txt
