spl_parse_image_header() is that function I am talking about.
There is this checking
image_get_magic(header) == IH_MAGIC
where IH_MAGIC is 0x27051956 which is old u-boot image format.

What I thought that you have is support for images in doc/uImage.FIT
format in u-boot SPL.
Just to have kernel/dtb/ramdisk in one file.

Thanks,
Michal
