Then it might also be broken. I have the same situation on SAR2130P,
ADSP works, but CDSP crashes. Please separate modem to a separate series
and clearly mark that it is not supposed to work. Until it works on any
of the boards I don't think we should be merging corresponding driver
bits, which are known-broken.
