Hopefully 1.2 corresponds to some actual version numbering and not just 
something you made up. I'd really rather have SoC based compatible 
strings unless you have dozens of SoCs for each version. I'll probably 
just say the same thing again when 1.3 or 2.0 gets added...

No, these are coming from the HW. They are user visible.
