Feb 1, 2026

February 2026 monthly summary for qualcomm-linux/meta-qcom focusing on RB3Gen2 and Arm-based Open Boot Firmware and OP-TEE integration. Overview: Delivered Open Boot Firmware (OBF) capabilities for Arm platforms, added RB3Gen2 support with open firmware stack, and introduced OP-TEE security enhancements. These changes enable unsigned and signed boot workflows, TF-A-based boot chain, and secure runtime components, aligning with Arm SystemReady standards and improving platform security, reliability, and deployment flexibility across production RB3Gen2 systems.

Dec 1, 2025

Month: 2025-12 — Summary of work on flipperdevices/u-boot focused on stability and SDHCI reliability. Implemented a DLL control hook to disable the core DLL when the bus clock is at or below 100 MHz, improving stability and performance in the MSM SDHCI driver. The change includes an SDHCI ops hook (config_dll) and a minimal DLL control routine, aligning with upstream Linux MSM SDHCI behavior. Patch is submitted with a full Signed-off-by chain and references upstream patch link, demonstrating adherence to kernel development practices. This work reduces low-clock instability in the MMC/SD subsystem and contributes to more reliable boot-time and device operation across affected platforms.
