| * This function is used as part of the facility to provide secure buffer |
| * memory. A default implementation is provided but it can be replaced by |
| * the SoC implementor if necessary. |
| * |
| * Calling this function will create a PMR for a memory allocation made |
| * in "secure buffer memory". It will only be writable by a trusted |
| * entity and when the feature is enabled on the SoC the GPU will only |
| * be able to perform operations permitted by security rules. |
