/* FIXME:
*
* 1. Although all of the necessary command mapping places have the
* appropriate dma_map.. APIs, the driver still processes its internal
* queue using bus_to_virt() and virt_to_bus() which are illegal under
* the API. The entire queue processing structure will need to be
* altered to fix this.
* 2. Need to add memory mapping workaround. Test the memory mapping.
* If it doesn't work revert to I/O port access. Can a test be done
* safely?
* 3. Handle an interrupt not working. Keep an interrupt counter in
* the interrupt handler. In the timeout function if the interrupt
* has not occurred then print a message and run in polled mode.
* 4. Need to add support for target mode commands, cf. CAM XPT.
* 5. check DMA mapping functions for failure
* 6. Use scsi_transport_spi
* 7. advansys_info is not safe against multiple simultaneous callers
* 8. Add module_param to override ISA/VLB ioport array
