From: Simon Glass <sjg@chromium.org> This series implements support for Microsoft's Computer Hardware Identifier (CHID) specification in U-Boot. CHIDs provide a standardised way to identify hardware configurations using SMBIOS data, enabling automatic selection of appropriate device tree overlays and drivers when the firmware itself lacks support for devicetree. The CHID system generates UUIDs from various combinations of hardware information (manufacturer, product name, BIOS version, etc.) creating a hierarchy from most to least specific. This allows U-Boot to automatically select the correct devicetree compatible-string for the hardware on which it running. This series includes: * Core CHID Infrastructure: - UUID v5 generation with Microsoft's CHID namespace - Support for all 15 CHID variants (HardwareID-00 through HardwareID-14) - SMBIOS data extraction and processing * Devicetree Integration: - hwids_to_dtsi.py script to convert CHID files to devicetree .dtsi - Automatic inclusion of the .dtsi into the board'' devicetree - Runtime compatible-string-selection based on hardware CHIDs * chid command: - chid show - show current hardware information and generated CHIDs - chid list - list all supported CHID variants and generated UUIDs - chid variants - show information about CHID variant restrictions - chid compat - select the compatible string for current hardware * ARM/EFI Support: - CHID mappings for a selection of ARM-based Windows devices - Support for Qualcomm Snapdragon platforms (MSM8998, SC7180, SC8180X, SC8280XP, SDM850, X1E series) * Testing: - Sandbox tests using mock SMBIOS data - CI integration for hwids_to_dtsi validation - Validation against Microsoft's ComputerHardwareIds.exe output Documentation is provided for this new subsystem and associated commands. Simon Glass (25): lib: Rename gen_v5_guid() to indicate it is little-endian uuid: Refactor v5 GUID generation into BE and LE variants smbios: Correct logic in smbios_get_header() smbios: Update smbios_get_header() to return a void * smbios: Expand the documentation smbios: Provide a sandbox test smbios: Improve comments for entry-point structures smbios: Add comments for smbios_type1 (System Information) smbios: Add docs for the main types test: Add more SMBIOS data to sandbox efi: arm: Provide CHIDs for the app efi: arm: Provide a mapping from CHIDs to compatible chid: Create a basic CHID header and smbios interface chid: Provide a command to access chid features uuid: Add a constant for the length of a UUID chid: Support calculating values for each variant chid: Add subcommand for dealing with variants chid: Provide some developer docs scripts: Add a tool to convert CHIDs to devicetree CI: Plumb in the hwids_to_dtsi tests sandbox: Provide hwid files for testing Makefile: Integrate CHID files into the build chid: Implement selection of the compatible string chid: doc: Describe how the CHID feature works cmd: chid: Add 'compat' subcommand to find compatible string
