+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
