Thanks, merged to master as of b6ebee077d915916989aa3057239a985981edb07.

Does it make sense to also have a --skip-stb-header option?

I don't like us relying on the stb header just being 4096 bytes, but
IIRC everywhere else hardcodes it too... I'm mostly wondering about not
building too much knowledge of host firmware into OpenBMC.
