The libfdt functionality was written by David Gibson.  The original

source came from the Git repository:

URL:		git://ozlabs.org/home/dgibson/git/libfdt.git

author		David Gibson <dgibson@sneetch.(none)>

		Fri, 23 Mar 2007 04:16:54 +0000 (15:16 +1100)

committer	David Gibson <dgibson@sneetch.(none)>

commit		857f54e79f74429af20c2b5ecc00ee98af6a3b8b

tree		2f648f0f88225a51ded452968d28b4402df8ade0

parent		07a12a08005f3b5cd9337900a6551e450c07b515

To adapt for U-Boot usage, only the applicable files were copied and

imported into the U-Boot Git repository.

Omitted:

  * GPL - U-Boot comes with a copy of the GPL license

  * test subdirectory - not directly useful for U-Boot

After importing, other customizations were performed.  See the

"git log" for details.
