+ This FSP API provides multi-phase memory and silicon initialization, which brings greater modularity to the existing
+ FspMemoryInit() and FspSiliconInit() API. Increased modularity is achieved by adding an extra API to FSP-M and FSP-S.
+ This allows the bootloader to add board specific initialization steps throughout the MemoryInit and SiliconInit flows as needed.
+ The FspMemoryInit() API is always called before FspMultiPhaseMemInit(); it is the first phase of memory initialization. Similarly,
+ the FspSiliconInit() API is always called before FspMultiPhaseSiInit(); it is the first phase of silicon initialization.
+ After the first phase, subsequent phases are invoked by calling the FspMultiPhaseMem/SiInit() API.
+ The FspMultiPhaseMemInit() API may only be called after the FspMemoryInit() API and before the FspSiliconInit() API;
+ or in the case that FSP-T is being used, before the TempRamExit() API. The FspMultiPhaseSiInit() API may only be called after
+ the FspSiliconInit() API and before NotifyPhase() API; or in the case that FSP-I is being used, before the FspSmmInit() API.
