Long Jumping Linux 2.6...5.10
summary
Migrates three real products—from 2.6.x to 5.10 SLTS—successfully running Gen3 middleware on Gen3+ hardware; work targets 3 legacy targets (ARMv4, ARMv5, PowerPC MPC8321) and finishes a functional port in about three months of initial porting plus 3–4 months of automotive testing. Key moves: device-tree migration of board logic, move heavy features into modules + initramfs, handle NAND page-size and partition constraints, update u-boot and adopt u-boot 2009→2020 with FIT images, and build BSPs with Yocto (Kirkstone); result: working field-capable systems.
