-Routine Description:
-
- Loads a PE/COFF image into memory, this is not follow the original purpose of
- PeCoffGetEntryPoint library class. But it's ok that Unix package not run on a real
- platform and this is for source level debug.
-
-Arguments:
-
- Pe32Data - Pointer to a PE/COFF Image
-
- EntryPoint - Pointer to the entry point of the PE/COFF image
-
-Returns:
-
- EFI_SUCCESS if the EntryPoint was returned
- EFI_INVALID_PARAMETER if the EntryPoint could not be found from Pe32Data
