/* 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
