Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition.

An OTP memory region. Some flashes provide a one-time-programmable

memory whose content can either be programmed by a user or is already

pre-programmed by the factory. Some flashes might provide both.
