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.

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