Greetings,
In updating some of the boards for 2.6, I've encountered one without
an 8259. I can either stub-out the call to i8359_irq() in my
board-specific code or pull the openpic_hookup_cascade() support forward
from 2.4. I've been told that the cascade approach is no longer in
favor, but I have not been able to locate an alternative. So, does
anyone have a recommendation on how to proceed?
Thanks,
Randy Vinson

Yes, we wanted to do better but never found the time to do so. I
suppose pulling the 2.4 approach in 2.6 is the best solution at this
point.
