Some image types, like "KeyStone GP", do not have magic numbers to distinguish them from other image types. Thus, the automatic image type discovery does not work correctly. This patch also fix some integer type mismatches. Signed-off-by: Guilherme Maciel Ferreira <guilherme.maciel.ferreira@gmail.com>
