And I think other A9 MPcore platforms, namely OMAP and EXYNOS, would
also be candidates, who tried to skip calibrate_delay() in the past
(OMAP) or currently provide non-smp_twd timers as localtimers (EXYNOS).
I may miss the latest status of those BSPs, but believe that we would
have more users (>2) in the future.
