This makes the timer code a little more self-contained. Signed-off-by: Arnd Bergmann I tested this series on a couple of different ColdFire parts (5208 and 5475) and under QEMU emulating the 5208. All checked out good, all worked as expected.

[PATCH 05/13] m68k: coldfire: use legacy_timer_tick()
Replace the indirect function calls in the timer code with direct calls to the newly added legacy_timer_tick() helper for those that have not yet been converted to generic clockevents. This makes the timer code a little more self-contained.
