| * Intel FSP-M configuration |
| |
| Several Intel platforms require the execution of the Intel FSP (Firmware |
| Support Package) for initialization. The FSP consists of multiple parts, one |
| of which is the FSP-M (Memory initialization phase). |
| |
| This binding applies to the FSP-M for the Intel Apollo Lake SoC. |
| |
| The FSP-M is available on Github [1]. |
| For detailed information on the FSP-M parameters see the documentation in |
| FSP/ApolloLakeFspBinPkg/Docs [2]. |
| |
| The properties of this binding are all optional. If no properties are set the |
| values of the FSP-M are used. |

| |
| Optional properties: |
| - fspm,training-delay: Time taken to train DDR memory if there is no cached MRC |
| data, in seconds. This is used to show a message if possible. For Chromebook |
| Coral this is typically 21 seconds. For an APL board with 1GB of RAM, it may |
| be only 6 seconds. |
