There is a flag in both multiboot and multiboot2 image indicating modules must be loaded to page boundaries. Currently this flag is not handled when loading multiboot images in ELF format. Check this flag and move the loaded modules if needed before SetupMultibootInfo(). Signed-off-by: Jiaqing Zhao <jiaqing.zhao@intel.com>
