Some platforms have the means to determine the counter frequency at runtime, so give them an opportunity to do so.
Aside from the one comment I already made, the series,

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.
