libfdt: Copy the struct region in fdt_resize()

2019-07-29T15:38:06+00:00

At present this function appears to copy only the data before the struct
region and the data in the string region. It does not seem to copy the
struct region itself.

>From the arguments of this function it seems that it should support fdt
and buf being different. This patch attempts to fix this problem.

libfdt: Add phandle generation helper

2019-04-12T02:10:50+00:00

The new fdt_generate_phandle() function can be used to generate a new,
unused phandle given a specific device tree blob. The implementation is
somewhat naive in that it simply walks the entire device tree to find
the highest phandle value and then returns a phandle value one higher
than that. A more clever implementation might try to find holes in the
current set of phandle values and fill them. But this implementation is
relatively simple and works reliably.

Also add a test that validates that phandles generated by this new API
are indeed unique.

pylibfdt: Use Python 2 in Makefile

2019-01-15T20:28:45+00:00

pylibfdt needs Python 2 to build.
Replace $(PYTHON) with $(PYTHON2) in pylibfdt Makefile
to ensure Python 2 is used to build it.

This fixes build on systems where Python 3 is the default version
of the "python" interpreter.

libfdt: Update to latest pylibfdt implementation

2018-08-08T11:49:36+00:00

The enhanced pylibfdt support in U-Boot needed for binman was a
placeholder while upstreaming of this work continued. This is now
complete, so bring in the changes and update the tools as needed.

There are quite a few changes since we decided to split the
implementation into three fdt classes instead of two.

The Fdt.del_node() method was unfortunately missed in this process and
will be dealt with later. It exists in U-Boot but not upstream.

Further syncing of libfdt probably needs to wait until we assess the
code-size impact of all the new checking code on SPL and possibly provide
a way to disable it.

libfdt: Add get_property() and del_node()

libfdt: Fix the Python pack() function

This currently fails to reduce the device-tree bytearray size. Fix this.

This stands in for a pending upstream change.

libfdt: Bring in proposed pylibfdt changes

2018-07-09T15:11:00+00:00

This provides various patches sent to the devicetree-compiler mailing list
to enhance the Python bindings. A final version of this patch may be
created once upstreaming is complete, but if it takes too long, this can
act as a placeholder.

New pylibfdt features:
- Support for most remaining, relevant libfdt functions
- Support for sequential-write functions

Changes are applied to existing U-Boot tools as needed.

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")
