Thank you for reviewing my patch.

I didn't know that it is a mandatory requirement that CONFIG_SYS_HZ == 1000.
I grep'ed for CONFIG_SYS_HZ in README and under doc/, but I could not find any description about it.

  $ grep -r CONFIG_SYS_HZ README doc/*
  doc/README.LED:(CONFIG_SYS_HZ / <N>) where <N> is the frequency of the blink. Typical values

And I couldn't find that what value should be return in ulong get_timer(ulong base);
I hope "how to implement system timer" documented.
