My goal is only to say what is the SoC model name in the /proc/cpuinfo
(And it is not an OMAP-only solution - it is common. Support for OMAP
is added in second patch)
This is the only type of information that we can apply for any SoC.
My point is - any SoC-specific information should go through some other
way - like SoCinfo framework mentioned by you.
And additional point - in cpuinfo we already have CPU name and Machine name.
The SoC name (that is something between these two things) looks also relevant

Yes, let's have additional comments
