Interrupts in U-boot

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

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.
