Well, this is the reason we have a separate function / command (clocks)
that can be called only when needed. Generally, we avoid to print too
much information if they are not required and can slow down the boot
process.

In print_cpuinfo() we output the processor type, the revision if it is
available and maybe the processor frequency - nothing more. And if we
need a complete overview of the clocks, there is the "clocks" command.

So really I prefer the patch as it is - the information printed are the
same as for other SOCs, not only i.MX.

Best regards,
