* Intel FSP-S 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-S (Silicon initialization phase). This binding applies to the FSP-S for the Intel Apollo Lake SoC. The FSP-S is available on Github [1]. For detailed information on the FSP-S 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-S are used.
