On the whole, I don't think the zero-length transfers are too
egregiously bad, and all the alternatives seem worse to me.

So why not turn the CS line into GPIO and just toggle the GPIO?

Does that work with *all* SPI controllers?

It does not - no. See my other email.

And is that line an actual CS of that lattice chip or a generic input
which almost works like CS?
