This workflow job uses the non-persisting build job type, so it won't contribute to the shared workspace/caches and may repeatedly rebuild the MrChromebox coreboot toolchain from scratch each run. If you want faster iteration and/or reusable caches, consider using build_and_persist (and adding coreboot-mrchromebox paths to save_cache).

Minor text issues in the board header comment: "a Acer" should be "an Acer", and "Wi-FI" should be "Wi-Fi".

export CONFIG_AUTO_BOOT_TIMEOUT is defined twice (line 67 and again at the end). This duplication is easy to miss and can cause confusing overrides—please keep a single definition.

Suggested change
export CONFIG_AUTO_BOOT_TIMEOUT=5
