When building Exynos boards, configure OF_UPSTREAM_VENDOR to build all
device trees in:
 - "samsung/" for 32-bit ARM platforms.
 - "exynos/" for 64-bit ARM platforms.

Our last sync with the kernel was 5.1.

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,
but that's what we decided during a community call for the bump to 5.1,
so we are following the same guidelines here.

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.

Anshul Dalal <anshuld@ti.com> says:

This patch series adds support for AM6254atl SiP (or AM62x SiP for
short) to U-Boot.

The OPN (Orderable Part Number) 'AM6254atl' expands as follows[1]:

AM6254atl
     ||||
     |||+-- Feature Lookup (L indicates 512MiB of integrated LPDDR4)
     ||+--- Device Speed Grade (T indicates 1.25GHz on A53 cores)
     |+---- Silicon PG Revision (A indicates SR 1.0)
     +----- Core configuration (4 indicates A53's in Quad core config)

AM62x SiP provides the existing AM62x SoC with 512MiB of DDR
integrated in a single packages. The first 4 patches in the series
are cherry-picked from the devicetree-rebasing repository at
'v6.18-rc2-dts'.

This patch adds the dt for SK-AM62-SIP, which uses the existing
SK-AM62 board design with the new AM6254atl SiP. This changes the
location of memory node from the board dts to SoC level dtsi
(k3-am6254atl in our case).

Therefore this patch introduces the new 'k3-am625-sk-common.dtsi'
which represents the common hardware used for both 'am625-sk' and
'am6254atl-sk' boards with the inheritance hierarchy modified to:

k3-am625-sk.dts:

     k3-am62    k3-am62x-sk-common
        |            |
    k3-am625    k3-am625-sk-common
        |            |
        +-----+------+
              |
         k3-am625-sk

k3-am6254atl-sk.dts:

     k3-am62
        |
     k3-am625       k3-am62x-sk-common
        |                |
    k3-am6254atl    k3-am625-sk-common
        |                |
        +-------+--------+
