Good question.

> AT91 still has some values like that in global_data, yesterday David M?ller 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 ;-)

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 ...

bye,
Heiko
