** Description changed:

  [Impact]
- Drivers for the HiSilicon Hi1616 and Hi1620 SoCs continue to be under active 
development, including both hardware enablement and bug fix patches. With the 
amount of flux involved, identifying and cherry-picking individual patches 
would be more error prone then re-syncing with current upstream periodically.

would be more error prone then re-syncing with current upstream.
  
  [Test Case]
+ The Ubuntu server certification suite, which includes network and storage 
tests.
  
  [Fix]
- Various upstream patches.
+ Backport the localized driver changes up to v5.0-rc1.
  
  [Regression Risk]
- The number of changes here obviously comes with regression risk. However, 
these drivers are only used for two HiSilicon SoCs and their corresponding 
development platforms - D05 and D06. We are therefore able to mitigate the risk 
by directly testing these changes on the impacted devices.
+ These changes are restricted to the hns and hisi_sas drivers, which only 
impact the D05 and D06 server development board platforms. To mitigate this 
risk, we have explicitly tested the proposed changes on these 2 platforms. Of 
course, there is risk that these changes introduced regressions that our 
testing did not catch.
