+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.
