May 1, 20252025-05 monthly summary for flipperdevices/u-boot. Focused on delivering hardware boot support improvements and stabilizing the Kirkwood DM_SERIAL path, alongside hardening ext4fs error handling. Key outcomes include: 1) DM_SERIAL support across Kirkwood boards including DS109 and removal of DS109-specific reset_misc in favor of a generic U-Boot reset; 2) Ext4fs fix for read-outside-partition with correct block-number types and elevated error reporting; 3) Codebase simplification and improved maintainability for the Kirkwood DM_SERIAL path; 4) Clear commit traceability with the associated changes listed below. This work improves boot reliability, device compatibility, and triage efficiency for field and production scenarios.
