Please keep lists sorted.

Line to long. And please try to stick with a consistent error message
format.

Ditto, and so on. Please fix globally.

I cannot understand this code.

How about using TABs to make this easier to read, say:

static struct image_type_params imximage_params = {
	.name		= "Freescale i.MX 51 Boot Image support",
	.header_size	= sizeof(struct imx_header),
	.hdr		= (void *)&imximage_header,
	.check_image_type = imximage_check_image_types,
	.verify_header	= imximage_verify_header,
	.print_header	= imximage_print_header,
	.set_header	= imximage_set_header,
	.check_params	= imximage_check_params,
};
