No board support is enabled, and the board code for KZM9G DT Reference is left by itself.

But that is how things have played out. And the result seems to be that Morimoto-san's patch will resolve a regression that has been queued up for v3.20. With the above in mind I plan to queue up the change below as a fix for v3.20.
