January 2026 focused on delivering upstream-ready PPC Qoriq/mpc85xx platform enhancements and stabilizing CI. Key items include moving the patch from mpc85xx to generic/pending to enable upstream patching and improving failsafe reliability by aligning preinit with the primary LAN/first DSA port. Fixed build CI issues by correcting T4240RDB u-boot variant selection to prevent buildbot crashes and rootfs installation problems. Overall impact: higher upstream readiness, reduced CI instability, and improved platform reliability across Qoriq targets. Technologies demonstrated include kernel patching, upstream processes, mpc85xx, u-boot, patch management, and CI optimization.

Dec 1, 2025

December 2025 monthly summary for DragonBluep/openwrt. Focused on enabling the internal Curve25519 cryptographic library for the Qoriq target, and cleaning up unused kernel configurations to improve security posture and maintainability. Despite a lean feature set this month, the work establishes a stronger cryptographic baseline for Qoriq-based OpenWrt devices and reduces reliance on external crypto libraries. No major bugs were reported this period. The work lays the groundwork for faster cryptographic operations and easier kernel maintenance going into 2026.
