[snip another ARM-SoC add to GD for timer]
can't this generalized in some way?
Good question.
AT91 still has some values like that in global_data, yesterday David Müller sent a patch for S3C24X0 to add some values like that to global_data ... we have a lot of arm cores out there, should each get his own style of global_data?
A common way would be better, ideas are welcome ;-)
I think Reinhard is already thinking about a solution.
For example we could rename for the armv7 timer variants the "lastinc" and "lastdec" value in "lastval", so we could merge them ... if it is possible to find a solution for all arm cores, I don;t know ...
A short look to the arm/cpu/**/timer.c showed that most of them use a 16 bit timer to provide an 32 bit timer value. For that class of timer implementation it would be suffucient to have a 'uint32_t last_timer_val' and an 'uint32_t timestamp' in GD.
