6.9 Copyrights and Licensing
U-Boot is Free Software. It is copyrighted by Wolfgang Denk and many others who contributed code (see the actual source code
for details). You can redistribute U-Boot and/or modify it under the terms of version 2 of the GNU General Public License as
published by the Free Software Foundation. Most of it can also be distributed, at your option, under any later version of the
GNU General Public License -- see individual f iles for exceptions.
NOTE! This license does *not* cover the so-called "standalone" applications that use U-Boot services by means of the jump
table provided by U-Boot exactly for this purpose - this is merely considered normal use of U-Boot, and does *not* fall under
the heading of “derived work”.
The header files “include/image.h” and “include/asm-*/u-boot.h” def ine interfaces to U-Boot. Including these (unmodified)
header f iles in another f ile is considered normal use of U-Boot, and does *not* fall under the heading of “derived work".
Also note that the GPL below is copyrighted by the Free Software Foundation, but the instance of code that it refers to (the U-
Boot source code) is copyrighted by me and others who actually wrote it.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General
Public License is intended to guarantee your freedom to share and change free sof tware -- to make sure the software is free
for all its users. This General Public License applies to most of the Free Software Foundation's sof tware and to any other pro-
gram whose authors commit to using it. (Some other Free Software Foundation sof tware is covered by the GNU Library General
Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure
that you have the freedom to distribute copies of free sof tware (and charge for this service if you wish), that you receive source
code or can get it if you want it, that you can change the sof tware or use pieces of it in new free programs; and that you know
you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the
rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify
it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights
that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so
they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permis-
sion to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for
this free sof tware. If the software is modif ied by someone else and passed on, we want its recipients to know that what they
have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.
