There is, namely "reg". How to best describe flash chips
interleaved on the bus is still an open problem. And things
like combining two sequential in address space flash chips
into a virtual one, or describing flash "partitions" doesn't
belong in the device tree at all; it is a policy thing, not
a hardware thing.
