Humm, that LICENSE file needs to be double-checked. Is there any reason 
why the text of this LICENSE.sof is different the usual text, e.g. from 
the LICENSE.adsp_sst?

You are missing both the first part:

***** INTEL BINARY FIRMWARE RELEASE LICENCE ********************************

Redistribution.

Redistribution and use in binary form, without modification, are permitted
provided that the following conditions are met:
*    Redistributions must reproduce the above copyright notice and the
      following disclaimer in the documentation and/or other materials 
provided
      with the distribution.
*    Neither the name of Intel Corporation nor the names of its

      be used to endorse or promote products derived from this software 
without
      specific prior written permission.
*    No reverse engineering, decompilation, or disassembly of this 
software is
      permitted.

and the DISCLAIMER part, both of which seem pretty important to me. 
IANAL, but seeing only a patent clause looks odd. There should be a 
mention of redistribution and a clear disclaimer (not sure about the 
reverse engineering parts since the code is available it makes no sense).

There are two types of platforms, the ones which require the Intel 
firmware to be signed with a private production key and the ones that 
are signed with the SOF community key.

if we have a single directory, then how do we deal with the two cases? 
It's not even clear to me which of the two cases are handled here.

unless I am missing something, we don't have any tables in the Linux 
kernel for the WHL and CML configurations, and IIRC we only generate 
sof-cnl.ri. Is there actually a user for sof-whl.ri and sof-cml.ri?
