You can drop Lauri from CC , I think this address is dead.

Note sure about that:

Given that u-boot.bin and spl/u-boot-spl.bin are packed into u-boot.sb , this is 
why you always see a different u-boot.sb .

The patch is good, I have just a minor rant below, otherwise add my:

Acked-by: Marek Vasut <marex@denx.de>

btw. you can check if the image was not corrupted by issuing:

$ mkimage -l u-boot.sb

Why don't we use 'MKIMAGE' here to be consistent ? Or 'MXSIMAGE' if we want to 
differentiate ?

Invokation seems OK to me. Getting rid of the 'sed' call is really to my liking 
here :)

Thank you!
