This is a good design policy for new hardware. However, there are two
holes:

- the imperfections of existing hardware, i.e., GTA02, and

- the PMU won't do us the favour of being in a nicely defined
  state after CPU reset.

So we still need to solve this initialization problem, even if we can
reduce its scope in future hardware.
