Aside from the one comment I already made, the series,

Acked-by: Stephen Warren <swarren@nvidia.com>
Tested-by: Stephen Warren <swarren@nvidia.com>

I validated that the calculated clk_m rate is correct on p2371-2180 when
booted under L4T's nvtboot. I didn't validate the programming of
cntfrq_el0, since I'm booting at EL2 not EL3. Still, that part is
trivial and the same code as in start.S.

Tom, this series would replace my patch "ARM: tegra: fix
COUNTER_FREQUENCY for T210". Or perhaps apply my patch then fix up the
minor conflicts when applying this series. That would at least document
the fact that COUNTER_FREQUENCY was wrong in all the initial header
files, in case someone looks back at old git versions.
