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.

For some of the Qualcomm SoC's, it is possible that the qfprom region is
|
|
protected from non-secure access. In such situations, the OS have to use
|
|
secure calls to read the region.
