As the talk is going in SPI framework direction, therefore requesting again..
please do not clutter the *generic* SPI framework to pass on opcodes from
flash-driver (like m25p80). (Q)SPI framework should remain generic and
independent of any upper layer drivers.
Therefore I proposed DT based approach, as an alternative.

But as Shijie's patches are centric to FSL use-case and qspi-controller,
so I cannot pursue my suggestions further.
