1 | U-Boot is Free Software. It is copyrighted by Wolfgang Denk and |
| 2 | many others who contributed code (see the actual source code and the | |
| 3 | git commit messages for details). You can redistribute U-Boot and/or | |
| 4 | modify it under the terms of version 2 of the GNU General Public | |
| 5 | License as published by the Free Software Foundation. Most of it can | |
| 6 | also be distributed, at your option, under any later version of the | |
| 7 | GNU General Public License -- see individual files for exceptions. | |

| 9 | NOTE! This license does *not* cover the so-called "standalone" | |
| 10 | applications that use U-Boot services by means of the jump table | |
| 11 | provided by U-Boot exactly for this purpose - this is merely | |
| 12 | considered normal use of U-Boot, and does *not* fall under the | |
| 13 | heading of "derived work" -- see file Licenses/Exceptions for | |
| 14 | details. | |
| 15 | ||
| 16 | Also note that the GPL and the other licenses are copyrighted by | |
| 17 | the Free Software Foundation and other organizations, but the | |
| 18 | instance of code that they refer to (the U-Boot source code) is | |
| 19 | copyrighted by me and others who actually wrote it. | |

| 23 | Like many other projects, U-Boot has a tradition of including big | |
| 24 | blocks of License headers in all files. This not only blows up the | |
| 25 | source code with mostly redundant information, but also makes it very | |
| 26 | difficult to generate License Clearing Reports. An additional problem | |
| 27 | is that even the same licenses are referred to by a number of | |
| 28 | slightly varying text blocks (full, abbreviated, different | |
| 29 | indentation, line wrapping and/or white space, with obsolete address | |
| 30 | information, ...) which makes automatic processing a nightmare. | |
| 31 | ||
| 32 | To make this easier, such license headers in the source files will be | |
| 33 | replaced with a single line reference to Unique License Identifiers | |
| 34 | as defined by the Linux Foundation's SPDX project [1]. For example, | |
| 35 | in a source file the full "GPL v2.0 or later" header text will be | |
| 36 | replaced by a single line: | |
| 37 | ||
| 38 | SPDX-License-Identifier: GPL-2.0+ | |
| 39 | ||
| 40 | We use the SPDX Unique License Identifiers here; these are available | |
| 41 | at [2]. | |
