I've connected a SanDisk compact flash to the 8260 local bus and have the interrupt pin wired to ~IRQ1 of the 8260. When I call function 'request_8xxirq' what interrupt number should I be requesting?
The 8260 User's manual says that IRQ1 is interrupt number 19, but if I request that interrupt number it does not work.

That's the correct number to use. Have you configured the rest of the
interrupt controller properly? You need to at least configure SIEXR
for level/edge and SIUMCR to enable the IRQ1 pin. Of course, this means
you can't enable external snooping due to pin multiplexing, so I hope
that's OK in your system design.
