In the sys/config package, there are two main flags to test against in
code, depending on your implementation:
* CONFIG_FCB (storage in FCB)
* CONFIG_NFFS (storage in NFFS)
https://github.com/apache/mynewt-core/blob/master/sys/config/syscfg.yml
I'd like to add config key-pairs as an option to a sensor driver (the
TSL2591 I submitted a PR for), to reload the integration time and other
settings on startup, and persist changes when made, but am I correct
that there isn't a single higher level 'CONFIG' flag and I'll need to
test against both of the values above to determine if the config system
is present or not? It seems not, but maybe I'm missing something.
Would anyone else consider it 'cleaner' to add a single flag that is
defined in either case (more if another persistance layer is added in
the future), since the API itself makes FCB or NFFS (or ???) mostly
transparent?

PS: As a side note, persisting the NFFS partition to an external file
under ARCH_sim would make certain test cases easier., storing values
across reets and builds. If this seems useful to anyone, I can raise it
as a Github issue and look at putting a PR together?
