Marc Zyngier and David Feng had objections to this when I posted[0]. I ended up solving this differently, by initializing the architectural timer earlier and then using the architected timer on ARM64. I'll post the two patches I have in my tree as a replacement for this and sorry for causing such a mess. Thierry [0]: http://lists.denx.de/pipermail/u-boot/2015-March/208505.html
