Dear Joe,

Yes, the license is a concern. I'm not a lawyer, but maybe someone can comment on what our options are here. Wolfgang? Tom?
IANAL...
Fact is, we already have some 80+ source files in U-Boot which are covered by the BSD-3-Clause license. Apparently there are also statements from the FSF that BSD-3-Clause is considered compatible with GPLv2.
My _personal_ opinion is that I try to avoid BSD-3-Clause because of both the:
2. Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution.
and the
3. The name of the author may not be used to endorse or promote products derived from this software without specific prior written permission.
clauses.
The former forces me to add "some text" to all documentation, and the latter forbids me to say who wrote the code as this might be considered promotion of the product. Both are obligations I have to adhere to, while GPL clearly says "You may not impose any further restrictions on the recipients' exercise of the rights granted herein." So in my opinion BSD-3-Clause should be avoided - but then, this is just my $0.02 - YMMV.
I take chances to have lwIP relicenced under a dual license (GPLv2 OR BSD-3-Clause) are epsilon?
Best regards,
Wolfgang Denk
