Support for old NVMEM fixed cells was deprecated in favour of "fixed-layout". It's still part of the nvmem.yaml though and may be unknowingly used by new bindings added without much of analyze. To make it more difficult to accidentally support old syntax move its binding to separated file with "deprecated" in its name.

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.
