2022-04-16IntelFsp2Pkg: X64 compatible changes to support PEI in 64bitTed Kuo1-5/+5
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3893 1.Added EFIAPI to FspNotifyPhasePeimEntryPoint, SwapStack and PEI_CORE_ENTRY. 2.Treat both MAX_ADDRESS and MAX_UINT32 as invalid address for FSP global data in FspApiCallingCheck(). 3.Changed AsmReadEsp to AsmReadStackPointer. 4.Changed the type of the return value of AsmReadStackPointer from UINT32 to UINTN. 5.Changed the type of TemporaryMemoryBase, PermenentMemoryBase and BootLoaderStack from UINT32 to UINTN. 6.Some type casting to pointers are UINT32. Changed them to UINTN to accommodate both IA32 and X64. 7.Corrected some typos.

2019-01-28IntelFsp2Pkg: FSP can utilize bootloader stackChasel, Chiu1-0/+28
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.
