Thanks again Arnd. I did that yesterday and got it working last night!
The only thing I have questions about are:
1) Since this is for a quasi realtime application, is there any
advantage to using the interrupt line regarding how the CPU spends its
idle time waiting for the flash? (I have an interrupt line I can use.)
Currently I am not sending in the IRQ resource, resource array length of
2, not 3.
2) I am getting this message during boot up: "Driver 'sd' needs
updating - please use bus_type methods". Again this is kernel 2.6.26.
It seems like this can be safely ignored, but if its easy to get rid of
that I would be happy to back port a patch.
I really appreciate your help.
