- Nobody uses this driver in practice, as the hardware platform
  was a dead end

Depends what you mean with dead end.

The hardware was deployed in a few million handsets from Samsung
and Sony.

Some have been picked up as targets for PostmarketOS:
https://wiki.postmarketos.org/wiki/Samsung_Galaxy_S_Advance_(samsung-i9070)
https://wiki.postmarketos.org/wiki/Samsung_Galaxy_SIII_mini_(samsung-i8190)

So it is no more dead end than anything else discontinued, and it
has a living community who want it suppored by the mainline
kernel if possible.

I meant that when ST-Ericsson imploded, STMicroelectronics inherited the
SoC family but never did any follow-up chips. We only really ever supported the
original U8500 but not the later models (which have partial support), and that
is very unlikely to change, so all the devices that can run this
driver are already
known. This is only relevant because the dynamic allocation size depends on
the chip model.

Mixup with SuperH-based ST40?

No, but I wouldn't be surprised to find an ST40 inside the D40 engine ;-)
