This is a long story where for each new generation of
OMAP we used different approaches for creating
strings for SoCs names and revisions that this patch
fixes. It makes future exporting of this information
to SoC infrastructure easier.

Sorry I was not clear earlier with what I meant, but if
you remove static const char *cpu_rev here and use
soc_name and soc_rev here..

Okay, I understood what do you mean here. Will fix it in next patchset..
