* Pirelli DP-L10 has a bunch of extra chips supporting the WiFi/VoIP
and camera functions, chips for which there are no docs. I won't be
using any chips without docs in my design. The WiFi/VoIP function
is something I have no interest in at all (thus no plan of providing
any hw for that), and the first version won't have a camera either.
* The RF front end in my design will be quad-band; Pirelli is tri-band
(2EU+1US) just like Om. More GSM bands = freedom to travel to more
parts of the world with the device.
* I plan on connecting the USB-serial chip (probably CP2102, same as
Pirelli) to Calypso's MODEM UART, i.e., the more hw-capable out of
the two. In the existing Pirelli hw it is connected to the IrDA
UART, i.e., the less capable one. I would like to offer both RVTMUX
and the traditional AT command interface over this USB-serial port,
and TI's code wants to use the MODEM UART for CSD, not IrDA.
(Pirelli's fw does not provide an AT command interface, only some
proprietary i/f for their Weendoze PC software, built on top of TI's
