a message to stdout every time they run.

Remove this workaround, on the assumption that people have or will
upgrade to a newer version of dtc. This simplifies the build rule
significantly.

Related, split the invocation of cpp and dtc into separate commands
rather than a pipeline, so that if either fail, it is detected. This has
the nice benefit of saving off the result of the pre-processing step,

8 years agoLicenses: introduce SPDX Unique Lincense Identifiers
Wolfgang Denk [Fri, 21 Jun 2013 08:22:36 +0000 (10:22 +0200)]
Licenses: introduce SPDX Unique Lincense Identifiers

Like many other projects, U-Boot has a tradition of including big
blocks of License headers in all files.  This not only blows up the
source code with mostly redundant information, but also makes it very
difficult to generate License Clearing Reports.  An additional problem
is that even the same lincenses are referred to by a number of
slightly varying text blocks (full, abbreviated, different
indentation, line wrapping and/or white space, with obsolete address
information, ...) which makes automatic processing a nightmare.

To make this easier, such license headers in the source files will be
replaced with a single line reference to Unique Lincense Identifiers
as defined by the Linux Foundation's SPDX project [1].  For example,
in a source file the full "GPL v2.0 or later" header text will be
replaced by a single line:

        SPDX-License-Identifier:        GPL-2.0+

We use the SPDX Unique Lincense Identifiers here; these are available
at [2].

Note: From the legal point of view, this patch is supposed to be only
a change to the textual representation of the license information,
but in no way any change to the actual license terms. With this patch
applied, all files will still be licensed under the same terms they
were before.

Note 2: The apparent difference between the old "COPYING" and the new
"Licenses/gpl-2.0.txt" only results from switching to the upstream
version of the license which is differently formatted; there are not
any actual changes to the content.

Note 3: There are some recurring questions about linense issues, such
as:
    - Is a "All Rights Reserved" clause a problem in GPL code?
    - Are files without any license header a problem?
    - Do we need license headers at all?

The following excerpt from an e-mail by Daniel B. Ravicher should help
with these:

|
| That is a very fact specific analysis and could be different across the
| various files.  However, if the contributor could reasonably be expected
| to have known that the project was licensed GPLv2 or later at the time
| she made her contribution, then a reasonably implication is that she

|
| > - Do such files need any clean up, for example should we add GPL

|
| If the project as a whole is licensed under clear terms, you need not
| identify those same terms in each file, although there is no harm in
| doing so.

|
| It is not a conflict to grant a license and also reserve all rights, as
| implicit in that language is that you are reserving all "other" rights
| not granted in the license.  Thus, a file with "Licensed under GPL, All
| Rights Reserved" would mean that it is licensed under the GPL, but no
| other rights are given to copy, modify or redistribute it.
