(And third it will also eventually need to hook into the timer-based
delay framework that I think Nokia is working on to be really
useful, else all delays become unpredictable.)

Do you mean udelay()/mdelay() here ?

Yes. Stephen Boyd from Qualcomm has floated patches to fix it for the
ARM architecture, I just pushed him again. We use it in our
ST-Ericsson products.

I remember the post.

Ideally you'd want that to go along with the A15 timer stuff so that this
monotonic high-precision timer is also used for udelay()/mdelay().

The A15 counter which is always available and running can be used
to emulate this.
