I appreciate the answer, I think this topic has been discussed several times, so thanks for spending time re-visiting it once again. I have looked at both the examples/standalone code and the README.standalone. I have also seen 1) http://old.nabble.com/-U-Boot--How-to-get-GPL-free-standalone-programs-with-... [1] 2) http://lists.denx.de/pipermail/u-boot/2009-August/058650.html [2] 3) http://osdir.com/ml/boot-loaders.u-boot/2003-11/msg00072.html [3] 4) http://osdir.com/ml/freebsd.embedded/2008-01/msg00019.html [4] 5) http://old.nabble.com/Re%3A--U-Boot--How-to-get-GPL-free-standalone-programs... [5] Some of these are forums, rather that mailing lists, I apologize for not being specific in my previous message. The part that is not clear to me is if a conclusion has ever been reached as to the availability of a set of GPL-free headers that can be included in a stand-alone application. I think the GPL is quite valuable, but there are situations involving closed-source software where GPL licensed source files must be avoided (I'm sure this is news to nobody). Has such a set of GPL-free headers been developed, or must I develop them myself if I want to use them? In 5) above, you write

I have a question concerning standalone programs based on u-boot

This is the intention; if the current code or documentation should conflict with this intention, it should be fixed.
and
"exports.h" should be added to the "allowed" file list; there
should
be no need to include "common.h". Eventually this needs fixing. Patches are welcome.
In the latest U-Boot sources, this issue seems to still exist; headers available for inclusion in stand-alone application seem to include the GPL license language. I can't find equivalent headers that are "GPL-free", but maybe I am looking in the wrong place. This last comment includes mention of the "allowed" file list; I can't locate anything of this nature either.
