Julien, I might be misunderstanding what you wrote. MiniOS is BSD-2 so
MiniOS code can be integrated into a GPLv2 project without issues
(becoming GPLv2.)  So it should be OK to take MiniOS code and add it to
Uboot?

The other way around would be an issue: you cannot take GPLv2 code and
add it to a BSD-2 project.
