Add IntelFsp2Pkg and IntelFsp2WrapperPkg. Add FSP2.0 support. This series of patch is to support FSP2.0 specification at https://firmware.intel.com/sites/default/files/FSP_EAS_v2.0_Draft%20External.pdf Some major updates include: 1) One FSP binary is separated to multiple components: FSP-T, FSP-M, FSP-S, and optional FSP-O. Each component has its own configuration data region. 2) All FSP-APIs use same UPD format - FSP_UPD_HEADER. 3) Add EnumInitPhaseEndOfFirmware notifyphase. 4) FSP1.1/FSP1.0 compatibility is NOT maintained. 5) We also add rename Fsp* to FspWrapper* in IntelFsp2WrapperPkg, to indicate that it is for FspWrapper only. IntelFspPkg and IntelFspWrapperPkg will be deprecated. The new Intel platform will follow FSP2.0 and use IntelFsp2Pkg and IntelFsp2WrapperPkg. The old platform can still use IntelFspPkg and IntelFspWrapperPkg for compatibility consideration.

IntelFsp2Pkg: FSP can utilize bootloader stack REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1485 Current FSP utilizes pre-allocated temporary memory from boot loader for both heap and stack. To reduce overall temporary memory usage FSP may share the same stack with boot loader and only needs a smaller memory for heap, no separate memory required for stack. Setting PcdFspHeapSizePercentage to 0 to enable FSP sharing stack with boot loader, in this case boot loader stack has to be large enough for FSP to use. Default is 50 (half memory heap and half memory stack) for backward compatible with original model. Test: Verified on internal platform and booting successfully with both modes.

IntelFsp2Pkg: Support FSP Dispatch mode REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1241 Add support for both API (original mode) and DISPATCH mode: 1. Add FspMode field from reserved byte of Global Data Structure to tell which mode is selected by boot loader. If boot loader invoking FSP-M API this field will remain as default 0 (API mode), otherwise platform FSP should set this field to 1 (Dispatch mode) when initializing Global Data Structure. 2. gFspInApiModePpiGuid will be instaled when FSP running in API mode and modules only for API mode should have this in depex. 3. If it is DISPATCH mode, FSP will return to PEI dispatcher, not directly return to boot loader. 4. DISPATCH mode supports DXE NotifyPhase drivers so FSP will not wait for PEI NotifyPhase callbacks, instead it will install gFspReadyForNotifyPhasePpiGuid PPI for platform to complete late initialization before transferring to DXE. Test: Verified FSP API and DISPATCH modes on 2 internal platforms and both boot successfully.
