PS1, Line 9: Implementation of fill_lb_gpios() is not about VBOOT
> Majolica was the AMD reference board, but we wanted to boot chromeos on it. […]

fill_Lb_gpios() is an ugly piece of open-coding. The identifier strings should be enumerations, as the allowed choices come from the history of depthcharge so the specification is depthcharge git history?

It's odd to create lb_table entry for GPIOs, and not fill in any GPIO. Is it the case the payload fails if said lb_table is completely missing?
