reasonable. problem is, this and other boards apparently
contain programmed firmware (a “general”-purpose processor
plus memory &tc), and hence (design permitting) can present
whatever interface they like to the bus / main-CPU(s);
i.e., to the driver. the back-end logic needn't matter
a hoot, and can vary from model to model whilst the
interface remains “the same”. so guessing at a driver
based only on back-end logic can lead to confusing results
when there is intervening “smarts” closer to the bus.
disclaimer: I am not familar with either the boards or
chips specifically mentioned; only extrapolating from
the description and previous experience.
