Mattia Narducci restructured the Linux kernel boot documentation for ARM and AArch64 architectures in the flipperdevices/u-boot repository, focusing on improving maintainability and developer onboarding. By relocating architecture-specific documentation into the arch/ directory and updating environment links to reference current Linux kernel docs, Mattia ensured that developers could easily access accurate and up-to-date boot process information. The work, carried out using RST and documentation best practices, addressed the issue of stale references and reduced support queries. While the contribution was limited to a single feature over one month, it provided targeted improvements to documentation structure and long-term project clarity.
