I just thought it at first
but this wraps two files, with different license.

include/linux/libfdt_env.h:  GPLv2 only
scripts/dtc/libfdt/fdt*.c :  GPLv2+ or BSD-2-Clause


Looking at the include/linux/libfdt_env.h,
I thought GPLv2 only would be preferred for
the kernel-specific code.

If you prefer to align with scripts/dtc/libfdt/fdt*.c
I can change it, but I would also respect
the opinion from David Daney, the author of the
following commit:


commit ab25383983fb8d7786696f5371e75e79c3e9a405
Author: David Daney <david.daney@cavium.com>
Date:   Thu Jul 5 18:12:38 2012 +0200

    of/lib: Allow scripts/dtc/libfdt to be used from kernel code
