Licensing and contribution policy of dtc and libfdt
|
||||
===================================================
|
||||
|
||||
This dtc package contains two pieces of software: dtc itself, and
|
||||
libfdt which comprises the files in the libfdt/ subdirectory. These
|
||||
two pieces of software, although closely related, are quite distinct.
|
||||
dtc does not incoporate or rely on libfdt for its operation, nor vice
|
||||
versa. It is important that these two pieces of software have
|
||||
different license conditions.
|
||||
|
||||
As the copyright banners in each source file attest, dtc is licensed
|
||||
under the GNU GPL. The full text of the GPL can be found in the file
|
||||
entitled 'GPL' which should be included in this package. dtc code,
|
||||
therefore, may not be incorporated into works which do not have a GPL
|
||||
compatible license.
|
||||
|
||||
libfdt, however, is GPL/BSD dual-licensed. That is, it may be used
|
||||
either under the terms of the GPL, or under the terms of the 2-clause
|
||||
BSD license (aka the ISC license). The full terms of that license are
|
||||
given in the copyright banners of each of the libfdt source files.
|
||||
This is, in practice, equivalent to being BSD licensed, since the
|
||||
terms of the BSD license are strictly more permissive than the GPL.
|
||||
|
||||
I made the decision to license libfdt in this way because I want to
|
||||
encourage widespread and correct usage of flattened device trees,
|
||||
including by proprietary or otherwise GPL-incompatible firmware or
|
||||
tools. Allowing libfdt to be used under the terms of the BSD license
|
||||
makes that it easier for vendors or authors of such software to do so.
|
||||
|
||||
This does mean that libfdt code could be "stolen" - say, included in a
|
||||
proprietary fimware and extended without contributing those extensions
|
||||
back to the libfdt mainline. While I hope that doesn't happen, I
|
||||
believe the goal of allowing libfdt to be widely used is more
|
||||
important than avoiding that. libfdt is quite small, and hardly
|
||||
rocket science; so the incentive for such impolite behaviour is small,
|
||||
and the inconvenience caused therby is not dire.
|
||||
|
||||
Licenses such as the LGPL which would allow code to be used in non-GPL
|
||||
software, but also require contributions to be returned were
|
||||
considered. However, libfdt is designed to be used in firmwares and
|
||||
other environments with unusual technical constraints. It's difficult
|
||||
to anticipate all possible changes which might be needed to meld
|
||||
libfdt into such environments and so difficult to suitably word a
|
||||
license that puts the boundary between what is and isn't permitted in
|
||||
the intended place. Again, I judged encouraging widespread use of
|
||||
libfdt by keeping the license terms simple and familiar to be the more
|
||||
important goal.
|
||||
|
||||
**IMPORTANT** It's intended that all of libfdt as released remain
|
||||
permissively licensed this way. Therefore only contributions which
|
||||
are released under these terms can be merged into the libfdt mainline.
