We have HSIC support on the way in, so I do expect to be able to bring
up the modem rather soon. It's been a while since I worked on 8064, but
I believe that with some userspace tinkering (like making libqmi talk
PF_QIPCRTR) this would be good enough to camp on a network and send text
messages.

We will need a version of the rmnet driver (there's 5 different variants
in CAF) to do data based on this.

To get an audio call running we will have to figure out how to do DSP
based Audio, something we have punted on until now. But with new
requirements from DB820c we have to tackle this and I expect this to
benefit 8064 as well. We do know how to load the DSP firmware, so that
should be enough for the modem firmware not to go belly-up from the
get-go :)
