Actual behavior

(comments taken from coreboot source and FSP integration guide)
For what it's worth, we've considered this expected behavior and added a note to the support article that powering on more than once may be necessary after flashing is complete. There's also a PR open to add similar messaging in the Firmware Manager app. If/when this gets fixed, we may want to remove the corresponding notes from the documentation and GUI.
Cause may not be the same, but this is going to become very apparent after the coreboot update. coreboot will issue a global reset after changing the IME mode to put it in the correct state.
