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. Signed-off-by: Tom Rini <trini@konsulko.com>
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.

Tom Rini <trini@konsulko.com> says: 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 glob to catch these directories too. Reviewed-by: Peter Robinson <pbrobinson@gmail.com> Signed-off-by: Tom Rini <trini@konsulko.com>
Ilias Apalodimas <ilias.apalodimas@linaro.org> says:
Last time the kbuild scripts were synced with the Linux kernel was on the
4.20 release. Updating directly to 6.x makes the diff difficult to read, so
let's do the changes incrementally and bump to 5.1 first.
Since the number of commits is big, I am splitting this in multiple series.
This one includes most of the commits for Makefile.build,
Makefile.lib and some from Makefile.
