Hello,

I need to call my board specific initialization routine before
timer_init or map_io is called.
I tried to see that in earlier architectures and found most of
architecture call machine
specific init function from map_io or init_irq or init_machine.

Situation: I need to register my clock framework with
arch/arm/common/clkdev framework
before actually initializing timer. So i can't do this in
"init_machine" as timer_init is called
before that.

One method would be to use an init call from <linux/init.h> which is
called before these are done (you'll have to work out which one is
suitable for yourself).

Either that or ensure that your boards always call a specific
routine in their init sequence to ensure clocks are registered before
the timer needs them.

If I remeber correctly, map_io() is actually called before the timers
are initialised, so you could add your clocks there.
