As part of debugging the appended device tree failure, I inadvertently
committed some changes as I was debugging to master, and not a private
branch, and pushed them as part of the release.
This reverts commit dc2d8423b19d30472b02e02b41504226908a4291 through
380ddb473c6bdf87e66c0fb93e256d1e233c6f5b.

When building with a toolchain that uses a modified sysroot (such as a
Yocto-generated SDK) that does not include libyaml, on a host that does
have libyaml, building dtc will fail with errors like:
HOSTLD scripts/dtc/dtc
/usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../x86_64-pc-linux-gnu/bin/ld:
scripts/dtc/yamltree.o: in function `yaml_propval_int':
yamltree.c:(.text+0x167): undefined reference to
`yaml_sequence_start_event_initialize'
/usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../x86_64-pc-linux-gnu/bin/ld:
yamltree.c:(.text+0x172): undefined reference to `yaml_emitter_emit'
/usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../x86_64-pc-linux-gnu/bin/ld:
yamltree.c:(.text+0x1e8): undefined reference to
`yaml_scalar_event_initialize'
/usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../x86_64-pc-linux-gnu/bin/ld:
yamltree.c:(.text+0x1f5): undefined reference to `yaml_emitter_emit'
(... rest of errors truncated ...)
This happens because the test looks for the file in the default path but
uses pkg-config, which is affected by changing sysroot, to determine the
correct linker arguments. This does not happen when building entirely
within yocto, as pseudo will intercept and rewrite the file path when
trying to test for /usr/include/yaml.h to match the sysroot and thus
generate consistent behavior.
This commit adds the PKG_CONFIG_SYSROOT_DIR prefix to the file path
in order to test against the same conditions that are used to resolve
the build flags for libyaml.
In linux commit ef8795f3f1c ("dt-bindings: kbuild: Use DTB files for
validation"), including yaml is disabled again anyway because of other
problems that it causes, so this problem can also be addressed by
partially backporting that commit instead and simply disabling the yaml
support.

Add a requirements.txt file to the pylibfdt script directory to specify
setuptools as a dependency. This follows the pattern of each tool in
U-Boot having its own requirements.txt file. The version is set to
78.1.1 to avoid conflict with the same in tools/patman/requirements.txt.

Replace usage of $(srctree) with $(abs_srctree) when creating a symlink
to include/asm/arch in out of tree builds.
When building_out_of_srctree is true, $(srctree) is just "..", so the
created symlink was broken, for example:
build-mt8365_evk/include/asm/arch -> ../arch/arm/include/asm/arch-mediatek
Which would resolve to a non-existent path:
build-mt8365_evk/include/asm/arch/arm/include/asm/arch-mediatek
To fix, we need to use the absolute path to the source tree since we
don't know where the build tree is located relative to the source tree.

U-Boot requires Kconfig options to be indented with tabs, whereas Linux
allows spaces. Add a U-Boot specific check to warn when spaces are used
for indentation in Kconfig files.
To ensure this check is executed, move the u_boot_line() invocation in
process() to occur before the valid source file check. Previously,
Kconfig files were skipped by the file extension filter before the
U-Boot specific checks could run.
Example warning:
WARNING: Kconfig indentation should use tabs
+ bool

DEVICE_TREE_DEBUG=1
In case DEVICE_TREE_DEBUG is set, produce a diff between the base DT and
DT with U-Boot extras, to show how much does the U-Boot DT differ from
the base DT. This is particularly useful together with OF_UPSTREAM, to
minimize the diff between upstream DTs and U-Boot DTs.
This requires DTC 1.7.2 which does not resolve phandles when used in
the 'dtc -I dts -O dts ...' mode. With older DTC, the diff is full of
churn due to the resolved phandles.
Example usage:
$ make r8a779g3_sparrowhawk_defconfig && make DEVICE_TREE_DEBUG=1
$ cat ./dts/upstream/src/arm64/renesas/r8a779g3-sparrow-hawk.dtb.diff

We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.
This is an attempt to sync up Makefiles to 6.1.
Unfortunately due to sheer amount of patches this is not easy to review,

Support for using "u-boot,dm-..." rather than "bootph-..." has been
deprecated since February 2023. Any platforms using this have had a
console message saying to migrate by 2023.07. Go and remove all support
here now, for the v2026.01 release.
The results of this change that aren't clear from the above are that we
still have a checkpatch.pl error message, and document in
doc/develop/spl.rst that they have been migrated since 2023. We also
change the key2dtsi.py tool to use the correct bootph phase rather than
the legacy phase.

On more recent versions of setuptools the warning about not being able
to find the files specified in license_files has re-appeared. This is
because as best I can tell, it can't and won't look in $(srctree) but
rather only subdirectories of scripts/dtc/pylibfdt. Since we already
provide both SPDX tags and a license field with the SPDX contents, let
us just drop license_files as it's not mandatory.

Our last sync with the kernel was 5.1. Even that was a partial one
as some patches from 4.x kernels were already missing making the
transition to a modern kbuild infeasible.
We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.
This is an attempt to sync up Makefile[.lib/.kbuild].
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call.
One of the biggest changes is get rid of partial linking entirely and
build .a archives isntead of .o.
We diaviate from the kernel on that. Instead of calling a custom script
to create the archive symbol table, we call ar with rcTP (isntead of
rcSTP) since we want a resulting archive that's sauble with the linker.
The only affected platforms are PPC ones. Unfortunately I don't have any
of them around to test, but the objdump of the resulting files --
arch/powerpc/lib/built-in.[oa] looks identical.

Since commit 51ec8db23280 ("pylibfdt: correct license information"), the
License classifiers are gone so I assume setuptools now extract the
license from the license argument to setuptools.setup() function.
It's always been incorrect as far as I could tell, so let's fix this
with the appropriate info from the SPDX License identifier at the top of
the file. It was missing GPL-2.0-or-later and we disambiguate by using
BSD-2-Clause instead of simply BSD.

Taking inspiration from Heiko's patch[1] this series goes and cleans up
all of the arch/arm/dts/*.h files that can be easily removed. The big
challenge I ran in to here was that for some platforms that aren't using
OF_UPSTREAM were didn't have a sufficiently deep search path to find
files there rather than arch/arm/dts. This also showed that only ARM had
local header files to deal with.

A problem with the logic in upstream_dtsi_include currently is that it
does not list directories such as dts/upstream/src/arm/nxp/imx and so
will not findi "imx6ul-pinfunc.h" for example as it is normally and
correctly included without vendor sub-paths. Expand the current wildcard
