I've been thinking at the proper way to describe the binman partitions.
I am wondering if we should really extend the fixed-partitions
schema. This description is really basic and kind of supposed to remain
like that. Instead, I wonder if we should not just keep the binman
compatible alone, like many others already. This way it would be very clear
what is expected and allowed in both cases. I am thinking about
something like that:

Documentation/devicetree/bindings/mtd/partitions/brcm,bcm4908-partitions.yaml

this file is also referenced there (but this patch does the same, which
is what I'd expect):

Documentation/devicetree/bindings/mtd/partitions/partitions.yaml

I'll let the binding maintainers judge whether they think it's
relevant, it's not a strong opposition.

Right now this does not fit (I believe) the example. But if we no
longer extend fixed-partitions but just create binman.yaml, this will
probably be enough.
