6.3 Modules

Only modules in the board package should be modified in the process of board porting. The minimum platform package and other common package contents must not be directly modified. The board package and silicon package modules may have multiple instances to support different boards and different silicon. These components are required. They enable orderly board porting and add the support for extensibility in later stages. The libraries consumed are the subset of libraries required by this specification. Some libraries are defined in this specification, some are defined in EDK II documentation.

6.3.4 Platform Architecture Libraries

Board porting will require creation of libraries identified as produced by the BoardPkg. Depending on the board, there may be existing libraries that are sufficient for a board, so it is important to assess the utility of existing library instances when developing board support.
