[LinuxBIOS] Normal vs. fallback images and CMOS

[Jonathan Sturges]

Question.  If an embedded board has no battery backup, it should have no (usable) CMOS.  Therefore, is a "Normal" image required on such a system?  My understanding is that CMOS settings are required to force the Fallback image to boot, except in cases of an missing or corrupt Normal image.
I'm thinking I can pack in a bigger LB payload, if there's only need for one image.  Are there any considerations I'm missing?

Thanks,
Jonathan

It's rather the other way around. CMOS allows the Normal image to be
booted. So without CMOS you always boot the Fallback image. Which is
good, because Fallback uses the hardcoded default values for all
otherwise CMOS drives variables.

So just drop the Normal image.
