[edk2-devel] [edk2-platforms][PATCH V1 14/37] CoffeelakeSiliconPkg: Add package common library instances

Posted by Kubacki, Michael A 6 years, 4 months ago

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2082

Adds package-level library class instances.

* BaseConfigBlockLib - Library functions for config block management.
* BaseSiConfigBlockLib - Library functions for managing component
  config blocks.
* DxeAslUpdateLib - Services to update ACPI tables.
* PeiDxeSmmMmPciLib - Services to manage PCI Express addresses.
* PeiStallPpiLib - Installs an instance of EFI_PEI_STALL_PPI.
* PeiSiPolicyLib - Installs an instance of the Silicon Policy PPI.
  Prints the Silicon Policy PPI values when DEBUG prints are enabled.

Subject: [edk2-platforms][PATCH V1 14/37] CoffeelakeSiliconPkg: Add package common library instances

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2082

Adds package-level library class instances.

* BaseConfigBlockLib - Library functions for config block management.
* BaseSiConfigBlockLib - Library functions for managing component
  config blocks.
* DxeAslUpdateLib - Services to update ACPI tables.
* PeiDxeSmmMmPciLib - Services to manage PCI Express addresses.
* PeiStallPpiLib - Installs an instance of EFI_PEI_STALL_PPI.
* PeiSiPolicyLib - Installs an instance of the Silicon Policy PPI.
  Prints the Silicon Policy PPI values when DEBUG prints are enabled.
