Opt-in Fuse
There is a dedicated fuse for opt-in. Based on its value, quickboot decides whether to perform in-field ratchet update or to skip it.
If OEM wants to opt-in for in-field ratchet update, opt-in fuse should be programmed to 1. The quickboot checks whether the opt-in fuse is burned before proceeding with the hardware ratchet update. Note that this check is software enforced only.
