What do you mean by the "yet"? Does it mean that OTP info is planned to 
be added to the next SFDP version? Or does it mean that it is possible 
to discover it via SFDP but we just don't support it yet?

If it is neither and it just means "SFDP does not mention OTP at all", 
like it is for locking, then you should just drop the "yet". I know this 
is very nitpicky but it just caught my eye.

Why not move this to late_init() as well?
