U-Boot's New Standard Boot and What's Next
summary
Standard Boot replaces brittle DRO scripts and messy environment variables with a C-driven system that discovers OS images via bootdev/bootmeth plugins and hunters, exposes choices through a bootflow command and a customizable expo UI, and ships ~5,000 lines of tests. Binman builds complex firmware images automatically. Measured KVM/QEMU handoff time reaches about 82 ms on the presenter’s machine. Migration requires small config/header edits and some boards are already upstream.
