Yes, you're correct.  I tested it and checked it against the
specification.

As for the high value of CFG_HZ: yes, while testing I also
had overflow troubles.  But as the relevant function is in CPU
support and not in board support, it's not possible to change
it without breaking all the boards based on this CPU.
To avoid the overflow problem, it might help to add a
mdelay() and maybe even sleep() function.
