[edk2-devel] [edk2-platforms][PATCH V2 3/6] CoffeelakeSiliconPkg: Clean up duplicated SmramMemoryReserve.h files
Posted by Marc W Chen 6 years, 5 months ago 
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2108

SmramMemoryReserve.h has been added into
Edk2\MdePkg\Include\Guid\SmramMemoryReserve.h.

The duplicated header file can be cleaned up.
Edk2Platforms\Silicon\Intel\CoffeelakeSiliconPkg\SampleCode\IntelFrameworkPkg\Include\Guid\SmramMemoryReserve.h
