Oh I forgot to mention - feel free to send a patch for that. I mainly 
didn't add such a message earlier, since I when I wrote the U-Boot 
header generator in tegra-pinmux-scripts, I wanted to generate exactly 
the same data as was already there in U-Boot in the manually written 
files. If you think updating those files to add a "this is 
auto-generated" message would be useful, feel free to send a patch to 
tegra-pinmux-scripts and we can add it.
