If `where we're at' is trying to boot an ARMv7 product, then you can boot in
secure svc and lose virtualisation support. Looking forward to ARMv8, this
isn't going to work, so I'd encourage you to start thinking about getting
a working bootloader as a requirement.

Yup, definitely on the same page now.  With everyone working on this
I'd imagine that there will be some nice standards worked out by the
time real ARMv8 is ready to ship?

...so would you say that you're in support of landing the patch to
allow physical counters?  I know Olof has Acked the patch above, but
it's nice if there's general agreement that it's OK.

I'm in favour of fixing the regression, yes. What I didn't understand from
the patch is where arch_timer_use_virtual is set to false for your machine,
as we need to be careful not to regress arm64 (the vdso uses the virtual
counter there).
