In some setups, one image can be used with several versions, or even
different boards of hardware. The bootloader passes a command line
argument to specify this. Also, the header file for the mkbootimg
specifies that the "kernel_args[] is appended to the kernel
commandline". So I thought this would make it consistent with other
bootloaders, and the spec.

Thanks for the tip.
I'll try to write a test if I get the time.
One thing comes to mind. To be able to write a test, we'll need an image
to test against. I think pulling in the mkbootimg tool is the right move.
The other option I can think of is bundling a small dummy image with
U-Boot, which I think is a bit ugly. What do you think?
