-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.
