The tiny To/Cc list above is probably because this file isn't mentioned
in MAINTAINERS, please add myself, Neil, and Sumit (see the ARM
SNAPDRAGON section in MAINTAINERS) on the next revision, thanks.

As I understand it, smem is a bit of a dumping ground of various
different data, some of which is standard across all boards and some is
not... A lot of the values you're adding here seem specific to this
modern set of IPQ-based dev boards. Could you document what each of
these values actually does.

Likewise what what smem property do these correspond to?

Please document these structs, and which SMEM property they represent.
