Some images to be validated are relocated to a dynamic address at run time. So, these addresses cannot be known befor hand while signing the images and creating the header offline. So, support is required to pass the image address to the validate function as an argument. If an address is provided to the function, the address field in Header is not read and is treated as a reserved field.
