Bug description:
[Impact]
Intel released a new version sof firmware to Canonical, they suggested
that we should integrate the version v1.3-0f73628 and we should only
pick the cml and cnl firmwares since other firmwares are not fully
tested. Since we have a couple of Lenovo and Dell cnl and cml machines
which need to enable sof driver, we integrate the firmwares to
ubuntu.
[Fix]
- fix the hang issue in the firmware for the cml and cnl
- introduce the ldc file which helps to do the firmware debug
- divide the firmware to cml and cnl specific ones
[Test Case]
These firmwares are already widely used in oem project, the audio
functions worked very well under both Lenovo and Dell dmic machines.
[Regression Risk]
Low, Intel released these firmware to us, and we already did large
numbers audio test in the oem project.
