[Dimitri John Ledkov]

** Description changed:

  [Impact]
  
-  * HWE enablement
-  * This patch enables HBRT to use HYP special wakeup register in openBMC which until now was only used in FSP based machines.
+ - Without the fix, the system will crash on upstream hostboot with NMI enabled systems when opal-prd occ reset is triggered on OpenBMC boxes
+ - This patch enables HBRT to use HYP special wakeup register in openBMC which until now was only used in FSP based machines
  
- [Test Case]
+ [Testcase]
  
-  * TODO
+ - opal-prd occ reset
  
  [Regression Potential]
- 
-  * TODO
- 
-  * discussion of how regressions are most likely to manifest as a result
- of this change.
- 
-  * It is assumed that any SRU candidate patch is well-tested before
-    upload and has a low overall risk of regression, but it's important
-    to make the effort to think about what ''could'' happen in the
-    event of a regression.
- 
-  * This both shows the SRU team that the risks have been considered,
-    and provides guidance to testers in regression-testing the SRU.
+ - Failure of OCC reset command
  
  [Other Info]
-  
-  * Original bug report.

  On upstream hostboot with NMI enabled, opal-prd occ reset crashes. The following upstream patch needs to be backported to the package to avoid the error.
