Now that we are using absolute paths we can remove some of the sys.path mangling that appears in the tools. We only need to add the path to 'tools/' so that everything can find modules relative to that directory. The special paths for finding pylibfdt remain. Signed-off-by: Simon Glass <sjg@chromium.org>

"""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.rst
