[RFC/PATCH 0/2] Adding support to expose mtd flash otp regions via nvmem

Hi all,

attached series allows exporting mtd flash otp regions via nvmem.
This is my first stab and still needs cleanup, but I wanted to get some
general feedback on whether this can conceptually work.

In an earlier conversation with Boris (in Cc) he suggested (I think),
something similar to what I tried to implement.

If someone has suggestions (especially on how to deduplicate some of the parsing
code w.r.t to partitions I'd be happy to rework the series)

Thanks for your feedback,

Moritz
