**EntryPoint
40 Loads a PE/COFF image into memory, this is not follow the original purpose of
41 PeCoffGetEntryPoint library class. But it's ok that Unix package not run on a real
42 platform and this is for source level debug.

48 EntryPoint - Pointer to the entry point of the PE/COFF image
52 EFI_SUCCESS if the EntryPoint was returned

85 Returns the machine type of PE/COFF image.

87 The reason is NT32 package needs to load the image to memory to support source
