Hi Takashi,

The proposed method for handling the DSP load process looks fine to
us, and we can make a start on adding this to the CA0132 driver now.

We can update patch_ca0132.c, but would you be able to assist us with
the modifications to the hda_intel.c side at all? We think it might
result in a smoother process (and involving fewer submissions :) )
given your familiarity with the low-level architecture in that area.

If not, we'd appreciate any info or pointers you can provide on how
and where the necessary modifications need to be made to hda_intel.c.

Thanks again for all your help with this.
