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