We have lots of users for the existing legacy Baytrail/Cherrytrail 
driver and we cannot ask distributions to switch one sunny day.

I reached out to Hans and Jaroslav to understand how this deprecation 
might happen, and it has to be done in steps. First include the 
SOF/BYT-CHT driver in builds, experiment and test and after a successful 
test period switch over.

Keep in mind that Intel folks have only a very limited subset of the 
hardware based on BYT/CHT so we have to work with the community to get 
feedback, that's very different to Broadwell where there are only 3 
platforms to be supported and an extremely limited number of users 
impacted by a switch since we are out of the ChromeOS support period.

In all cases, distributions and users, not Intel, make the call.
