For the latter: this already doesn't support chips that use different
opcodes.

For the former: we're only talking about the "*-nonjedec" and similar,
right? I'm not confident those were supported well by this driver in the
first place. (And "*-nonjedec" should really die; if it's needed,
support should be added by design, not by accident.)

Perhaps Huang can comment.
