This doesn't seem realistic, you're assuming that system integrators
won't go and use chips you've not heard of and at least in the case of
things like quad read my understanding is that the commands aren't
standardised so the host just has to know what to write.

I'm not following? What are you suggesting?

Like I say I'm suggesting that the bit of the code that understands the
flash chip is separate to the bit of code that knows the mechanics of
sending commands and data to the chip.

After some analysis we have come to the conclusion that using m25p80
is not feasible. It makes more sense for this to be an
orthogonal/stand-alone driver.

That seems plausible for the controller side but it seems surprising for
the flash chip side.
