I would check with Andreas/PMM on what the go is with SoCs regarding
container devices and boards. My (vague) understanding is that SoCs
should be container devices and boards instantiate those containers
with off-chip connectivity. This seems flat to me, with everything on
board level.
Yes, thanks, that matches what I was going to comment. But I think it's
even more complicated: To my understanding, "sunxi" is the name of a
community effort [1] to clean up and upstream the BSP kernels from
Allwinner, so it sounds as if this was an attempt to write an emulation
for that kernel family while naming everything "sunxi" when in fact the
SoCs are called Axx [2] (with A1x = sun4i, A2x = sun5i, A3x = sun6i but
no literal "sunxi" AFAIK) and boards include Cubieboard, Cubieboard2,
Cubieboard3/Cubietruck [3] and whatever tablets etc. are out there.

That's a lesson we learned from the old "prep" machine: Please name
things after real hardware, only then can it later be verified whether
the modeling is actually correct or which changes need to be performed.
