As I have mentioned to you off list, I have (very) recently been
seconded into the Linaro Enterprise Group, focusing on improving the
ARM server software ecosystem.
As such, I am potentially in a bit of legal limbo, until Linaro signs
a contribution agreement. This is however in the works.
But giving some flexibility for roadblocks, can we say "this quarter"?

Apart from our *cough* convoluted architecture vs. processor naming
scheme... It should be ARMv4, ARMv5, ARMv6 and ARMv7.
(since ARM4 and ARM5 were skipped and ARM6 and ARM7 were processors
implementing the ARMv3 and ARMv4 architectures :)

I hope so.
