REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3893
1.Added EFIAPI to FspNotifyPhasePeimEntryPoint.
2.Changed AsmReadEsp to AsmReadStackPointer.
3.Changed the type of the return value of AsmReadStackPointer
from UINT32 to UINTN.
4.Changed the type of TemporaryMemoryBase, PermenentMemoryBase
and BootLoaderStack from UINT32 to UINTN.
5.Some type casting to pointers are UINT32. Changed them to
UINTN to accommodate both IA32 and X64.
6.Corrected some typos.

I guess it's possible that bootloader sets up the stack above 4G.
If that's the case, above code doesn't work.

[Ted]: I believe we already handled it in IntelFsp2Pkg/FspSecCore/X64/Stack.nasm in the patch [edk2-devel][PATCH v3 4/8] IntelFsp2Pkg: FspSecCore support for X64.

I guess it's possible that bootloader sets up the stack above 4G.
If that's the case, above code doesn't work.
[Ted]: The above code is for IA32 only. We have a separate ReadRsp.nasm for X64. You can find it in the patch [edk2-devel][PATCH v3 4/8] IntelFsp2Pkg: FspSecCore support for X64.
