-	  take the place of this one, and it is recommended that whenever
-	  possible, people should use the new Adaptec written driver instead
-	  of this one.  This driver will eventually be phased out entirely.
-
-	  This is support for the various aic7xxx based Adaptec SCSI

-	  2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and

-	  the AAA-13x RAID controllers from Adaptec, nor will it likely ever
-	  support them. It does not support the 2920 cards from Adaptec that
-	  use the Future Domain SCSI controller chip. For those cards, you
-	  need the "Future Domain 16xx SCSI support" driver.
-
-	  In general, if the controller is based on an Adaptec SCSI controller
-	  chip from the aic777x series or the aic78xx series, this driver
-	  should work. The only exception is the 7810 which is specifically
-	  not supported (that's the RAID controller chip on the AAA-13x
-	  cards).
-
-	  Note that the AHA2920 SCSI host adapter is *not* supported by this
-	  driver; choose "Future Domain 16xx SCSI support" instead if you have
-	  one of those.
-
-	  Information on the configuration options for this controller can be
-	  found by checking the help file for each of the available
-	  configuration options. You should read
-	  <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before

-	---help---
-	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
-	  are assigned to the drive letters, starting with the lowest SCSI-id
-	  (physical number -- pun) to be drive C:, as seen from DOS and
-	  similar operating systems. When looking into papers describing the
-	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
-	  The SCSI-standard follows a hardware-hierarchy which says that id 7
-	  has the highest priority and id 0 the lowest. Therefore, the host
-	  adapters are still today everywhere placed as SCSI-id 7 by default.
-	  In the SCSI-standard, the drive letters express the priority of the
-	  disk. C: should be the hard disk, or a partition on it, with the
-	  highest priority. This must therefore be the disk with the highest
-	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
-	  original definition of the SCSI-standard as also industrial- and
-	  process-control-machines, like VME-CPUs running under realtime-OSes
-	  (e.g. LynxOS, OS9) do.
-
-	  If you like to run Linux on your MCA-machine with the same
-	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
-	  machine, which is in addition conformant to the SCSI-standard, you
-	  must say Y here. This is also necessary for MCA-Linux users who want
-	  to keep downward compatibility to older releases of the
-	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
-	  June 1997).
-
-	  If you like to have the lowest SCSI-id assigned as drive C:, as
-	  modern SCSI-BIOSes do, which does not conform to the standard, but
-	  is widespread and common in the PC-world of today, you must say N
-	  here. If unsure, say Y.

-	  However, some devices exist, like special-control-devices,
-	  SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
-	  not reset when switched on. If you say Y here, each device connected
-	  to your SCSI-bus will be issued a reset-command after it has been
-	  probed, while the kernel is booting. This may cause problems with
-	  more modern devices, like hard disks, which do not appreciate these
-	  reset commands, and can cause your system to hang. So say Y only if

-	  Minimum is 2 and maximum is 14. This value is also the window size

+ * - Loss of BSY (cleared by reading RPIR)
+ * Two conditions have flag bits that are not latched:
+ * - Bus phase mismatch (non-maskable in DMA Mode, cleared by ending DMA Mode)
+ * - Bus reset (non-maskable)
+ * The remaining condition has no flag bit at all:
+ * - Selection/reselection
+ *
+ * Hence, establishing the cause(s) of any interrupt is partly guesswork.
+ * In "The DP8490 and DP5380 Comparison Guide", National Semiconductor
+ * claimed that "the design of the [DP8490] interrupt logic ensures
+ * interrupts will not be lost (they can be on the DP5380)."
+ * The L5380/53C80 datasheet from LOGIC Devices has more details.
+ *
+ * Checking for bus reset by reading RST is futile because of interrupt
+ * latency, but a bus reset will reset chip logic. Checking for parity error
+ * is unnecessary because that interrupt is never enabled. A Loss of BSY
+ * condition will clear DMA Mode. We can tell when this occurs because the
+ * Busy Monitor interrupt is enabled together with DMA Mode.

+ * NCR5380_abort - scsi host eh_abort_handler() method
+ * @cmd: the command to be aborted
+ *
+ * Try to abort a given command by removing it from queues and/or sending
+ * the target an abort message. This may not succeed in causing a target
+ * to abort the command. Nonetheless, the low-level driver must forget about
+ * the command because the mid-layer reclaims it and it may be re-issued.
  *
- * Purpose : abort a command
+ * The normal path taken by a command is as follows. For EH we trace this
+ * same path to locate and abort the command.
  *
- * Inputs : cmd - the Scsi_Cmnd to abort, code - code to set the 
- *      host byte of the result field to, if zero DID_ABORTED is 
- *      used.
+ * unissued -> selecting -> [unissued -> selecting ->]... connected ->
+ * [disconnected -> connected ->]...
+ * [autosense -> connected ->] done
  *
- * Returns : 0 - success, -1 on failure.
+ * If cmd was not found at all then presumably it has already been completed,
+ * in which case return SUCCESS to try to avoid further EH measures.
  *
- *	XXX - there is no way to abort the command that is currently 
- *	connected, you have to wait for it to complete.  If this is 
- *	a problem, we could implement longjmp() / setjmp(), setjmp()
- *	called where the loop started in NCR5380_main().
+ * If the command has not completed yet, we must not fail to find it.
+ * We have no option but to forget the aborted command (even if it still
+ * lacks sense data). The mid-layer may re-issue a command that is in error
+ * recovery (see scsi_send_eh_cmnd), but the logic and data structures in
+ * this driver are such that a command can appear on one queue only.
  *
- * Locks: host lock taken by caller
+ * The lock protects driver data structures, but EH handlers also use it
+ * to serialize their own execution and prevent their own re-entry.

-/* Notes:
- *
- * Most of the work is done in the chip specific module, 53c700.o
- *
- * TODO List:
- *
- * 1. Extract the SCSI ID from the voyager CMOS table (necessary to
- *    support multi-host environments.
- *
- * */
-
-
-/* CHANGELOG 
- *
- * Version 2.2
- *
- * Added mca_set_adapter_name().
- *
- * Version 2.1
- *
- * Modularise the driver into a Board piece (this file) and a chip
- * piece 53c700.[ch] and 53c700.scr, added module options.  You can
- * now specify the scsi id by the parameters
- *
- * NCR_D700=slot:<n> [siop:<n>] id:<n> ....
- *
- * They need to be comma separated if compiled into the kernel
- *
- * Version 2.0
- *
- * Initial implementation of TCQ (Tag Command Queueing).  TCQ is full
- * featured and uses the clock algorithm to keep track of outstanding
- * tags and guard against individual tag starvation.  Also fixed a bug
- * in all of the 1.x versions where the D700_data_residue() function
- * was returning results off by 32 bytes (and thus causing the same 32
- * bytes to be written twice corrupting the data block).  It turns out
- * the 53c700 only has a 6 bit DBC and DFIFO registers not 7 bit ones
- * like the 53c710 (The 710 is the only data manual still available,
- * which I'd been using to program the 700).
- *
- * Version 1.2
- *
- * Much improved message handling engine
- *
- * Version 1.1
- *
- * Add code to handle selection reasonably correctly.  By the time we
- * get the selection interrupt, we've already responded, but drop off the
- * bus and hope the selector will go away.
- *
- * Version 1.0:
- *
- *   Initial release.  Fully functional except for procfs and tag
- * command queueing.  Has only been tested on cards with 53c700-66
- * chips and only single ended. Features are
- *
- * 1. Synchronous data transfers to offset 8 (limit of 700-66) and
- *    100ns (10MHz) limit of SCSI-2
- *
- * 2. Disconnection and reselection
- *
- * Testing:
- * 
- *  I've only really tested this with the 700-66 chip, but have done
- * soak tests in multi-device environments to verify that
- * disconnections and reselections are being processed correctly.
