I don't think this is a good idea.

What you are doing here is defining an image format. Such an image
format must be good enough not only for OMAP4 and for loading U-Boot
as second stage, but for all other architectures and use cases as
well.

We therefore should be very careful not to oversimplify things here.
I suggest NOT to pot this information into the image itself, but
rather to prepend it (for example, using the mkimage tool), so the
actual payload image needs not to be modified.

Best regards,

Wolfgang Denk
