Yes it was. There is SPI-NOR on the cubie A7A. I did a quick sanity
check on it to verify it was functional (writing and reading back).
I should probably have added an note about that.

I have been submit a few changes like one lately. I'm doing that so we
can get on with DT as soon as possible, without waiting on the bindings.

I would normally submit the corresponding DT change at the same time
but DT is currently blocked by the main CCU and pinctrl.
