└─>SOF support for Broadwell
In linux kernel since version 5.1 (release Date: 2019-05-05)  
This adds support for Sound Open Firmware for Intel(R) platforms
using the Broadwell processors.
This option is mutually exclusive with the Haswell/Broadwell legacy
driver. If you want to enable SOF on Broadwell you need to deselect
the legacy driver first.
SOF does fully support Broadwell yet, so this option is not
recommended for distros. At some point all legacy drivers will be
deprecated but not before all userspace firmware/topology/UCM files
are made available to downstream distros.
Say Y if you want to enable SOF on Broadwell
If unsure select "N".
