Document the board compatible with coolpi,pi-4b as a fallback, extract the existing CoolPi 4B hardware description into a shared dtsi, and add a Sige7s DTS containing its model and compatible. The generated CoolPi 4B DTB is byte-for-byte identical before and after the extraction. The Sige7s device tree differs only in its root model and compatible properties. Boot-tested on an ArmSoM Sige7s v1.0 board, which successfully boots into userspace. This series retains the existing level of hardware support provided by the CoolPi 4B device tree. Validation: - Build-tested both DTBs with the arm64 defconfig and W=1. - Passed dt_binding_check for arm/rockchip.yaml. - Passed DTB validation against the full processed schema set. - Ran checkpatch --strict: no errors or checks; the two warnings ask whether MAINTAINERS needs updating for the added files. The files are covered by the existing subsystem entries. Product documentation: https://docs.armsom.org/armsom-sige7s AI assistance: Codex reviewed the series, ran the build and schema checks, revised the commit messages and cover letter.
