In arch/i386/core/Etherboot.prefix.lds _veratim_end is 16 byte align, So _verbatim_size is 16 byte align.
And in arch/i386/prefix/elf/prefix.S, phdr2_p_filesz is set to _verbatim_size...
But final tg3.elf size is not 16 byte align...
So I have to use "dd s=16 conv=sync " to make the image more big several bytes to 16 byte align...
