This patch add support for gpimage format as a preparatory patch for porting u-boot for keystone2 devices and is based on omapimage format. It re-uses gph header to store the size and loadaddr as done in omapimage.c Signed-off-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Acked-by: Tom Rini <trini@ti.com>
