4.3 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.

4.3.3. Platform Architecture Libraries (DXE)

Stage II contains some DXE items needed to enable Stage III. No board porting of these libraries is required. Board integrators should ensure that their silicon package provides the necessary libraries. These libraries and the UEFI Components (DXE) are functionally irrelevant to Stage II functionality.
