scripts/dtc: Re-sync with Linux 4.17-rc4

2018-05-31T12:53:11+00:00

To achieve a DTC state (more or less) equivalent to Linux 4.17-rc4,
backport the DTC-specific part from below Linux commits:

b23d1a241f4eb4 ("kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically")
9a8dfb394c0467 ("kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile")
59889300274569 (".gitignore: move *.lex.c *.tab.[ch] patterns to the top-level .gitignore")
e039139be8c251 ("scripts/dtc: generate lexer and parser during build instead of shipping")
b24413180f5600 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license")

With this commit, the diff between Linux and U-boot common DTC files is:
$ git diff --stat --diff-filter=M v4.17-rc4  -- scripts/dtc
  scripts/dtc/.gitignore | 2 +-
  scripts/dtc/Makefile   | 3 +++

The delta is coming from U-boot commits:
* v2017.11 de163ecedb8a ("scripts: dtc: Add .gitignore")
* v2018.01 15b97f5c5e6d ("pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile")

Commit c8b38f65fdec upstream ("libfdt: Remove leading underscores from

SPDX: Convert all of our multiple license tags to Linux Kernel style

2018-05-07T14:24:31+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

host-tools: use python2 explicitly for shebang

2018-01-28T17:27:30+00:00

All of these host tools are apparently written for Python2,
not Python3.

Use 'python2' in the shebang line according to PEP 394
(https://www.python.org/dev/peps/pep-0394/).

pylibfdt: compile pylibfdt only when dtoc/binman is necessary

2017-11-17T12:43:32+00:00

Currently, pylibfdt is always compiled if swig is installed on your
machine.  It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.

"checkbinman" and "checkdtoc" are wrong.  It is odd that the final
build stage checks if we have built necessary tools.  If your platform
depends on dtoc/binman, you must be able to build pylibfdt.  If swig
is not installed, it should fail immediately.

I added PYLIBFDT, DTOC, BINMAN entries to Kconfig.  They should be
property select:ed by platforms that need them.  Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

2017-11-17T12:43:32+00:00

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

  lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
  lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.
