Add a short test suite to demonstrate board-id selection and scoring.
This patch isn't intended to be merged here.
After compiling the kernel (esp. arch/arm64/boot/dts/qcom DTBs), run
tools/board-id/test.py.
The test cases provide a hypothetical firmware-provied board-id and

Add board-id to match sm8650 MTPs and QRDs.

The devicetree spec introduced a mechanism to match devicetree blobs to
boards using firmware-provided identifiers. Although the matching can be
implemented by DTB loaders, having a canonical implementation makes it
easier to integrate and ensure consistent behavior across ecosystems.
I've not yet
Introduce a tool which scores devicetrees based on their board-id and a
supplied reference devicetree. This mechanism would be most similar to
an proposal to EBBR where firmware provides a reference devicetree which
contains the actual board identifier values, and an OS loader can
choose to replace
Document board identifiers for devices from Qualcomm Technologies, Inc.
These platforms are described with two mechanisms: the hardware SoC
registers and the "CDT" which is in a RO storage.
The hardware SoC registers describe both the SoC (e.g. SM8650, SC7180)
as well as revision. Add qcom,soc to

Update existing documentation for qcom,msm-id (interchangeably:
qcom,soc-id) and qcom,board-id. Add support for qcom,pmic-id, qcom,oem-id
to support multi-DTB selection on Qualcomm's boards.
"qcom,soc-id", "qcom,board-id" and "qcom,pmic-id" are tuples of two 32-bit
values. The

Generic sm8550 devicetree is split into a dtsi. Move it into its own DTB
and preserve the boards as overlays.
When not using overlays, 264 KB needed to store the sm8550-mtp.dtb and
sm8550-qrd.dtb. When using overlays, 188 KB is needed to store
sm8550.dtb, sm8550-mtp.dtbo, and sm8550-qrd.dtbo; wher
In preparation for converting sm8550 to use devicetree overlays, use
phandles for thermal_zones.
