I first thought that in order to be allowed to incorporate GPL 3.0
code, Rockbox could be re-licensed under GPL version 2 or later[1].
However this is not true: the Rockbox project would need to upgrade
to GPL 3.0[2].

If Rockbox moved to GPL 3.0, this would prevent incorporating LGPL
(all versions) code, unless it would consist in linking to an
existing library. However, there seems to be an way around this:
existing code needs to be ported to Rockbox anyway, so a the new port
branch can be re-licensed under under GPL 3.0. Apparently, this is
allowed[3] since LGPL 2.1.

Otherwise there's always the WTFPL[4] aka "DO WHAT THE FUCK YOU WANT
TO PUBLIC LICENSE" :)

Regards, Dan
