Jakko said that the firmware distributed at linux-firmware.git
hardcodes the SSP to SSP2, while on some boards the codec may be
connected to SSP0, which could be my case.

That was the whole point of trying to reuse the firmware that was
working in my Android installation.

Any hint about how to extract the firmware from the ELF and convert it
to an SST firmware image usable with the upstream drivers? I could dig
into the sources and figure out the structures myself but maybe you have
some more accessible information.

Vinod, if you feel like catching up, the thread is also here:
http://thread.gmane.org/gmane.linux.alsa.devel/134554

I ask a lot of questions, I know.

Thanks,
   Antonio
