   *  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

   * The ASC-38C1600 Chip uses the same definitions except that the

   * offset 0xE (IOPB_SOFT_OVER_WR) bits [12:10]. The [12:10] bits in

   * is not needed. The [12:10] bits in IOPB_SOFT_OVER_WR are write-only.
   * Also each ASC-38C1600 function or channel uses only cable bits [5:4]
   * and [1:0]. Bits [14], [7:6], [3:2] are unused.

   * The advansys chip/microcode contains a 32-bit identifier for each command
   * known as the 'srb'.  I don't know what it stands for.  The driver used
   * to encode the scsi_cmnd pointer by calling virt_to_bus and retrieve it
   * with bus_to_virt.  Now the driver keeps a per-host map of integers to
   * pointers.  It auto-expands when full, unless it can't allocate memory.
   * Note that an srb of 0 is treated specially by the chip/firmware, hence
   * the return of i+1 in this routine, and the corresponding subtraction in
   * the inverse routine.

   *
   * The *_Field_IsChar structs are needed to correct for endianness.
   * These values are read from the board 16 bits at a time directly
   * into the structs. Because some fields are char, the values will be
   * in the wrong order. The *_Field_IsChar tells when to flip the
   * bytes. Data read and written to PCI memory is automatically swapped
   * on big-endian platforms so char fields read as words are actually being
   * unswapped on big-endian platforms.
