5.3 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.
