[edk2-platforms] [PATCH v2 1/7] CometlakeOpenBoardPkg: Add package and headers


Kathappan Esakkithevar
 

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2280

Create the CometlakeOpenBoardPkg to provide board support code. The
package may support Cometlake boards. The package serves as a board
support package in the EDK II Minimum Platform design. Silicon support
for this package is provided in CometLakeFspBinPkg in the FSP repository
and CoffeelakeSiliconPkg in the edk2-platforms repository.
