Sure. See examples/timer.c

There is, at least for some architectures...

The state is that interrups have been supported for a long, long time
without problems at least on PowerPC.

How would you compare this???
>reseaons an AT91RM9200 would work slower?
Did you enable caches?
BTW: chances to get answers to U-Boot related questions are MUCH
better on the u-boot-users mailing list.

Always try to do things in chronological order; it's less confusing
that way.

I am attempting to implement interrupt in u-boot, is
there any example code. I have noticed that some of
the code is implemented, however there are messages
which say there is no IRQ support in u-boot.
What does this mean?
What is the state of u-boot in this regard?
It seems u-boot is slower than linux? Are there any
reseaons an AT91RM9200 would work slower?
Clearly thats my target.
Thanks Nicholas Karsen
