This seems to me not the best solution. If we have now factored out code
to print the reset cause and the silicon version (inside print_cpuinfo),
why do we need to repeat this code for each board ? Calling get_cpu_rev
seems to me redundant (then each board should only set
CONFIG_DISPLAY_CPUINFO). And then the CPU revision is printed again, and
this is redundant.

As I see in code, in system_rev & 0xff we can find the cpu revision, and
the output is already part of print_cpuinfo.

I think we need more clean up, removing all part related to CPU revision
and leaving (if any) only the output related to the board revision.

Best regards,
Stefano Babic
