| 13 | Porting the TF-A Tests to a new platform involves making some mandatory and |
| 14 | optional modifications for both the cold and warm boot paths. Modifications |
| 15 | consist of: |
| 16 | |
| 17 | * Implementing a platform-specific function or variable, |
| 18 | * Setting up the execution context in a certain way, or |
| 19 | * Defining certain constants (for example #defines). |
| 20 | |
| 21 | The platform-specific functions and variables are all declared in |
| 22 | ``include/plat/common/platform.h``. The framework provides a default |
| 23 | implementation of variables and functions to fulfill the optional requirements. |
| 24 | These implementations are all weakly defined; they are provided to ease the |
| 25 | porting effort. Each platform port can override them with its own implementation |
| 26 | if the default implementation is inadequate. |
