I definitely agree we should not export every SoC-related information
just because we can do it.
The first goal of this interface was to export some SoCs IDs, as we need
this kind of information for some user-space tools.
Does someone need to export other information than the mach name and
some IDs?
As proposed in my previous mail, do you agree to have a unified file for
all vendors, which exports the unique silicon ID of the chip?
Regards,
Maxime
