> Subject: [edk2-platforms/devel-MinPlatform][PATCH 2/5]
> KabylakeSiliconPkg/DxeResetSystemLib: Add a new API ResetSystem
> 
> REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1460
> 
> Add a new API ResetSystem to this ResetSystemLib instance.
> It only adds the basic functions from ResetSystemRuntimeDxe.
> Lacking of this interface may cause link error, if some drivers use this new 
> API and
> link to this library instance.
> Make the ResetPlatformSpecific's parameters same with the interface in Edk2
> repo.
> Notes:
> This library API only provide a basic function of reset. If the consumers 
> want full
> functions, they should use the instance in the MdeModulePkg and make sure the
> depex driver is dispatched.
