Hi Jiewen/Ard/Sami/Supreeth,

 

I updated this patch in v2 to centralize common imp= lementations for certain library functions. Do you by any chance have more = comments on this patch? Any input is appreciated.

 

Regards,

Kun

Subject: [edk2-devel] [PATCH v3 03/18] StandaloneMmPkg: StandaloneM= mCoreHobLib: Extend support for x64 Mm Core

 

This change adds sup= port of x64 version of StandaloneMmCoreHobLib. It
brings in global variable "gHobList" through StandaloneMmCoreEnt= ryPoint,
imports implementation from DxeCoreHobLib.inf to support x64 Mm Core and moved shared functional plementations into a common file.

Notes:
    v3:
    - Pertains gHobList for AARCH64 instance.
   
    v2:
    - Moved common function implementations into Common.c [= Jiewen]
