I think it is simply the fact that (at least) for the Linux on the Cortex-A5 it
doesn't make any difference whether it's running on a 9615 or a 9215.
The difference is presumably primarily in the cellular radio interface
and possibly DSP capacity? From the few publicly available information
the 9615 adds Ev-DO (3GPP2) capability, while the 9215 is GSM/UMTS/LTE
(3GPP) only?
btw: I just created a new mailing list for any future public discussion
on the Qualcomm Linux based cellular modems, see

The 9200 is 3GPP-only and 9600 adds 3GPP2/EVDO, both without voice.
The 9215 and 9615 are the voice-enabled versins of both.

Hi,

indeed, but I was rather asking this, because it's probably better to look
around for documentation for 9215 then for 9615. Maybe some blocks are going
to be same, but who knows. I should probably download finaly the kernel
sources and look around to find this question myself :-)

Maybe it's the only difference, yes.

Good, thanks!
