Hi all,

I have a PCI card that has Intel Flash. I've cooked up a small driver (the
host kernel is 2.6.6) that iomaps the base address exported by the PCI BARs
and can verify that it's an intel flash by doing some config- write and
read sequences.

I now want to export the flash to userspace for reading / writing to the
flash. I guess it would be better to let MTD handle the stuff than me doing
things all over again. So, how can I access that flash memory over the PCI
with MTD?

Thanks for any hints,
Amit.

Look at
drivers/mtd/maps/pci.c and other files using PCI in the same folder
