When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

"""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
