All of the above sounds very good to me.

I'm just not sure about this part.

If we're going to have the STE fw ops linked together with the STE
module (which sounds really good btw), can the STE module just
directly do

rproc->fw_ops = ste_modem_fw_ops;

before calling rproc_register() ?

This way we're not exposing any other symbol, and things look pretty
clean and simple.

Thanks,
Ohad.
