** Description changed:

  [Impact]
- In our ubuntu kernel, the sof driver will load the sof-cnl.ri (firmware)
- on all platforms, but mainline kernel already supported the multi
- firmwares on differnt platforms, and OEM project needs us to
- support the mutli-firmware names in the ubuntu kernel
+ 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]
- cherry-pick 3 upstream patches, then on cnl platforms, it will
- load sof-cnl.ri, on cml platfomrs, it will load sof-cml.ri, on cfl
- platforms, it will load sof-cfl.ri
+  - 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]
- Prepare the firmware from https://github.com/thesofproject/linux-firmware
- master branch, then boot the kernel with these patches.
+ 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, just let different platforms load differnt firmware, and these
- patches are in the upstream kernel.
+ Low, Intel released these firmware to us, and we already did large
+ numbers audio test in the oem project.
