" summary

Generic BootLoader (GBL) is a Rust-based bootloader in AOSP built as a UEFI application that standardizes boot flow across ARM64 x86 and RISC‑V and plugs into U-Boot EDK2 or LittleKernel. It implements UEFI block I/O RNG and memory services, selects and patches Device Trees (DT/DTBO/FIT), prepares bootconfig/command line, and enforces A/B slot management plus AVB and Fastboot. Current uncompressed GBL is ~2 MB binary (debug builds 4–6 MB); ESP needs ~8 MB; goal is unified updates and faster security fixes.
