** 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.
