[PATCHv5 00/16] Unify arm_generic and arch_timer drivers

[mark.rutland@arm.com (Mark Rutland)]

This is an updated version of v4 of the series I posted 2 weeks ago [1].

The only change is the last two patches, moving over to always using the
virtual counters. I've left these as separate patches rather than
folding them in to allow them to be reviewed more easily.

I've tested the series on a TC2 and an AArch64 model, and I'm happy that
it all works.

Stephen, Thomas:

I've not folded the CLOCKSOURCE_OF_DECLARE patch as it's unclear what
path everything is going to take, and I don't a have a tree with
Stephen's patch that I can base on.

There's already a dependency on the timer broadcast rework, and adding
more branches to the mix is going to get messy. I can take the version
with ifdefs under the assumption we remove them in a later patch once
Stephen's patch is in. Does that sound ok?

Thanks,
Mark.
