There are a bunch of then in the kernel. Basically, you need to
search for your device on the pci_devices linked list, then do
something like:
phys_addr = device->base_address[0];
offset = phys_addr & ~PAGE_MASK;
io_addr = ioremap(phys_addr & PAGE_MASK,DEVICE_IO_SIZE)+offset;
And then use read[bwl]() and write[bwl]() to access the device using
the io_addr address.
