Hmm, perhaps not. But at least it isn't called :-)   I will tidy this
up when I get a response from the ARM maintainer.

While you are on the line, what is the plan with a general microsecond
timer in U-Boot? Is this on the cards, or is it still considered 'code
bloat'?

I am contemplating another crack at the bootstage patch (microsecond
boot timing) and it would help to know the plan on that front.

Simon
