Remove support for EATA and EATA-PIO SCSI host adapters.
These devices are ancient and, apparently, nobody is still
using them.

- *      eata.c - Low-level driver for EATA/DMA SCSI host adapters.
- *
- *      03 Jun 2003 Rev. 8.10 for linux-2.5.70
- *        + Update for new IRQ API.
- *        + Use "goto" when appropriate.
- *        + Drop eata.h.
- *        + Update for new module_param API.
- *        + Module parameters  can now be specified only in the
- *          same format as the kernel boot options.
- *
- *             boot option    old module param 
- *             -----------    ------------------
- *             addr,...       io_port=addr,...
- *             lc:[y|n]       linked_comm=[1|0]

- *             pp:[y|n]       pci_probe=[1|0]
- *
- *          A valid example using the new parameter format is:
- *          modprobe eata "eata=0x7410,0x230,lc:y,tm:0,mq:4,ep:n"
- *
- *          which is equivalent to the old format:

- *                        max_queue_depth=4 eisa_probe=0
- *
- *      12 Feb 2003 Rev. 8.04 for linux 2.5.60
- *        + Release irq before calling scsi_register.
- *
- *      12 Nov 2002 Rev. 8.02 for linux 2.5.47
- *        + Release driver_lock before calling scsi_register.
- *
- *      11 Nov 2002 Rev. 8.01 for linux 2.5.47
- *        + Fixed bios_param and scsicam_bios_param calling parameters.
- *
- *      28 Oct 2002 Rev. 8.00 for linux 2.5.44-ac4
- *        + Use new tcq and adjust_queue_depth api.
- *        + New command line option (tm:[0-2]) to choose the type of tags:
- *          0 -> disable tagging ; 1 -> simple tags  ; 2 -> ordered tags.
- *          Default is tm:0 (tagged commands disabled).
- *          For compatibility the "tc:" option is an alias of the "tm:"
- *          option; tc:n is equivalent to tm:0 and tc:y is equivalent to
- *          tm:1.
- *        + The tagged_comm module parameter has been removed, use tag_mode
- *          instead, equivalent to the "tm:" boot option.
- *
- *      10 Oct 2002 Rev. 7.70 for linux 2.5.42
- *        + Foreport from revision 6.70.
- *
- *      25 Jun 2002 Rev. 6.70 for linux 2.4.19
- *        + This release is the first one tested on a Big Endian platform:
- *          fixed endian-ness problem due to bitfields;
- *          fixed endian-ness problem in read_pio.
- *        + Added new options for selectively probing ISA, EISA and PCI bus:
- *
- *          Boot option   Parameter name    Default according to
- *
- *          ip:[y|n]      isa_probe=[1|0]   CONFIG_ISA  defined

- *          pp:[y|n]      pci_probe=[1|0]   CONFIG_PCI  defined
- *
- *          The default action is to perform probing if the corresponding
- *          bus is configured and to skip probing otherwise.
- *
- *        + If pci_probe is in effect and a list of I/O  ports is specified
- *          as parameter or boot option, pci_enable_device() is performed
- *          on all pci devices matching PCI_CLASS_STORAGE_SCSI.
- *
- *      21 Feb 2002 Rev. 6.52 for linux 2.4.18
- *        + Backport from rev. 7.22 (use io_request_lock).
- *
- *      20 Feb 2002 Rev. 7.22 for linux 2.5.5
- *        + Remove any reference to virt_to_bus().
- *        + Fix pio hang while detecting multiple HBAs.
- *        + Fixed a board detection bug: in a system with
- *          multiple ISA/EISA boards, all but the first one
- *          were erroneously detected as PCI.
- *
- *      01 Jan 2002 Rev. 7.20 for linux 2.5.1

- *
- *      19 Dec 2001 Rev. 7.02 for linux 2.5.1
- *        + Use SCpnt->sc_data_direction if set.
- *        + Use sglist.page instead of sglist.address.
- *
- *      11 Dec 2001 Rev. 7.00 for linux 2.5.1
- *        + Use host->host_lock instead of io_request_lock.
- *
- *       1 May 2001 Rev. 6.05 for linux 2.4.4
- *        + Clean up all pci related routines.
- *        + Fix data transfer direction for opcode SEND_CUE_SHEET (0x5d)
- *
- *      30 Jan 2001 Rev. 6.04 for linux 2.4.1
- *        + Call pci_resource_start after pci_enable_device.
- *
- *      25 Jan 2001 Rev. 6.03 for linux 2.4.0
- *        + "check_region" call replaced by "request_region".
- *
- *      22 Nov 2000 Rev. 6.02 for linux 2.4.0-test11
- *        + Return code checked when calling pci_enable_device.
- *        + Removed old scsi error handling support.
- *        + The obsolete boot option flag eh:n is silently ignored.
- *        + Removed error messages while a disk drive is powered up at
- *          boot time.
- *        + Improved boot messages: all tagged capable device are
- *          indicated as "tagged" or "soft-tagged" :
- *          - "soft-tagged"  means that the driver is trying to do its
- *            own tagging (i.e. the tc:y option is in effect);
- *          - "tagged" means that the device supports tagged commands,
- *            but the driver lets the HBA be responsible for tagging
- *            support.
- *
- *      16 Sep 1999 Rev. 5.11 for linux 2.2.12 and 2.3.18
- *        + Updated to the new __setup interface for boot command line options.
- *        + When loaded as a module, accepts the new parameter boot_options
- *          which value is a string with the same format of the kernel boot
- *          command line options. A valid example is:
- *          modprobe eata 'boot_options="0x7410,0x230,lc:y,tc:n,mq:4"'
- *
- *       9 Sep 1999 Rev. 5.10 for linux 2.2.12 and 2.3.17
- *        + 64bit cleanup for Linux/Alpha platform support
- *          (contribution from H.J. Lu).
- *
- *      22 Jul 1999 Rev. 5.00 for linux 2.2.10 and 2.3.11
- *        + Removed pre-2.2 source code compatibility.
- *        + Added call to pci_set_master.
- *
- *      26 Jul 1998 Rev. 4.33 for linux 2.0.35 and 2.1.111
- *        + Added command line option (rs:[y|n]) to reverse the scan order
- *          of PCI boards. The default is rs:y, which reverses the BIOS order
- *          while registering PCI boards. The default value rs:y generates
- *          the same order of all previous revisions of this driver.
- *          Pls. note that "BIOS order" might have been reversed itself
- *          after the 2.1.9x PCI modifications in the linux kernel.
- *          The rs value is ignored when the explicit list of addresses
- *          is used by the "eata=port0,port1,..." command line option.
- *        + Added command line option (et:[y|n]) to force use of extended
- *          translation (255 heads, 63 sectors) as disk geometry.
- *          The default is et:n, which uses the disk geometry returned
- *          by scsicam_bios_param. The default value et:n is compatible with
- *          all previous revisions of this driver.
- *
- *      28 May 1998 Rev. 4.32 for linux 2.0.33 and 2.1.104
- *          Increased busy timeout from 10 msec. to 200 msec. while
- *          processing interrupts.
- *
- *      16 May 1998 Rev. 4.31 for linux 2.0.33 and 2.1.102
- *          Improved abort handling during the eh recovery process.
- *
- *      13 May 1998 Rev. 4.30 for linux 2.0.33 and 2.1.101
- *          The driver is now fully SMP safe, including the
- *          abort and reset routines.
- *          Added command line options (eh:[y|n]) to choose between
- *          new_eh_code and the old scsi code.
- *          If linux version >= 2.1.101 the default is eh:y, while the eh
- *          option is ignored for previous releases and the old scsi code
- *          is used.
- *
- *      18 Apr 1998 Rev. 4.20 for linux 2.0.33 and 2.1.97
- *          Reworked interrupt handler.
- *
- *      11 Apr 1998 rev. 4.05 for linux 2.0.33 and 2.1.95
- *          Major reliability improvement: when a batch with overlapping
- *          requests is detected, requests are queued one at a time
- *          eliminating any possible board or drive reordering.
- *
- *      10 Apr 1998 rev. 4.04 for linux 2.0.33 and 2.1.95
- *          Improved SMP support (if linux version >= 2.1.95).
- *
- *       9 Apr 1998 rev. 4.03 for linux 2.0.33 and 2.1.94
- *          Added support for new PCI code and IO-APIC remapping of irqs.
- *          Performance improvement: when sequential i/o is detected,
- *          always use direct sort instead of reverse sort.
- *
- *       4 Apr 1998 rev. 4.02 for linux 2.0.33 and 2.1.92
- *          io_port is now unsigned long.
- *
- *      17 Mar 1998 rev. 4.01 for linux 2.0.33 and 2.1.88
- *          Use new scsi error handling code (if linux version >= 2.1.88).
- *          Use new interrupt code.
- *
- *      12 Sep 1997 rev. 3.11 for linux 2.0.30 and 2.1.55
- *          Use of udelay inside the wait loops to avoid timeout
- *          problems with fast cpus.
- *          Removed check about useless calls to the interrupt service
- *          routine (reported on SMP systems only).
- *          At initialization time "sorted/unsorted" is displayed instead
- *          of "linked/unlinked" to reinforce the fact that "linking" is
- *          nothing but "elevator sorting" in the actual implementation.
- *
- *      17 May 1997 rev. 3.10 for linux 2.0.30 and 2.1.38
- *          Use of serial_number_at_timeout in abort and reset processing.
- *          Use of the __initfunc and __initdata macro in setup code.
- *          Minor cleanups in the list_statistics code.
- *          Increased controller busy timeout in order to better support
- *          slow SCSI devices.
- *
- *      24 Feb 1997 rev. 3.00 for linux 2.0.29 and 2.1.26
- *          When loading as a module, parameter passing is now supported
- *          both in 2.0 and in 2.1 style.
- *          Fixed data transfer direction for some SCSI opcodes.
- *          Immediate acknowledge to request sense commands.
- *          Linked commands to each disk device are now reordered by elevator
- *          sorting. Rare cases in which reordering of write requests could
- *          cause wrong results are managed.
- *          Fixed spurious timeouts caused by long simple queue tag sequences.
- *          New command line option (tm:[0-3]) to choose the type of tags:
- *          0 -> mixed (default); 1 -> simple; 2 -> head; 3 -> ordered.
- *
- *      18 Jan 1997 rev. 2.60 for linux 2.1.21 and 2.0.28
- *          Added command line options to enable/disable linked commands
- *          (lc:[y|n]), tagged commands (tc:[y|n]) and to set the max queue
- *          depth (mq:xx). Default is "eata=lc:n,tc:n,mq:16".
- *          Improved command linking.
- *          Documented how to setup RAID-0 with DPT SmartRAID boards.
- *
- *       8 Jan 1997 rev. 2.50 for linux 2.1.20 and 2.0.27
- *          Added linked command support.
- *          Improved detection of PCI boards using ISA base addresses.
- *
- *       3 Dec 1996 rev. 2.40 for linux 2.1.14 and 2.0.27
- *          Added support for tagged commands and queue depth adjustment.
- *
- *      22 Nov 1996 rev. 2.30 for linux 2.1.12 and 2.0.26
- *          When CONFIG_PCI is defined, BIOS32 is used to include in the
- *          list of i/o ports to be probed all the PCI SCSI controllers.
- *          The list of i/o ports to be probed can be overwritten by the
- *          "eata=port0,port1,...." boot command line option.
- *          Scatter/gather lists are now allocated by a number of kmalloc
- *          calls, in order to avoid the previous size limit of 64Kb.
- *
- *      16 Nov 1996 rev. 2.20 for linux 2.1.10 and 2.0.25
- *          Added support for EATA 2.0C, PCI, multichannel and wide SCSI.
- *
- *      27 Sep 1996 rev. 2.12 for linux 2.1.0
- *          Portability cleanups (virtual/bus addressing, little/big endian

- *
- *  Here is a brief description of the DPT SCSI host adapters.
- *  All these boards provide an EATA/DMA compatible programming interface
- *  and are fully supported by this driver in any configuration, including
- *  multiple SCSI channels:
- *
- *  PM2011B/9X -  Entry Level ISA
- *  PM2021A/9X -  High Performance ISA
- *  PM2012A       Old EISA
- *  PM2012B       Old EISA
- *  PM2022A/9X -  Entry Level EISA
- *  PM2122A/9X -  High Performance EISA
- *  PM2322A/9X -  Extra High Performance EISA
- *  PM3021     -  SmartRAID Adapter for ISA
- *  PM3222     -  SmartRAID Adapter for EISA (PM3222W is 16-bit wide SCSI)
- *  PM3224     -  SmartRAID Adapter for PCI  (PM3224W is 16-bit wide SCSI)
- *  PM33340UW  -  SmartRAID Adapter for PCI  ultra wide multichannel
- *
- *  The above list is just an indication: as a matter of fact all DPT
- *  boards using the EATA/DMA protocol are supported by this driver,
- *  since they use exactely the same programming interface.
- *
- *  The DPT PM2001 provides only the EATA/PIO interface and hence is not
- *  supported by this driver.
- *
- *  This code has been tested with up to 3 Distributed Processing Technology
- *  PM2122A/9X (DPT SCSI BIOS v002.D1, firmware v05E.0) EISA controllers,
- *  in any combination of private and shared IRQ.
- *  PCI support has been tested using up to 2 DPT PM3224W (DPT SCSI BIOS
- *  v003.D0, firmware v07G.0).
- *
- *  DPT SmartRAID boards support "Hardware Array" - a group of disk drives
- *  which are all members of the same RAID-0, RAID-1 or RAID-5 array implemented
- *  in host adapter hardware. Hardware Arrays are fully compatible with this
- *  driver, since they look to it as a single disk drive.
- *
- *  WARNING: to create a RAID-0 "Hardware Array" you must select "Other Unix"
- *  as the current OS in the DPTMGR "Initial System Installation" menu.
- *  Otherwise RAID-0 is generated as an "Array Group" (i.e. software RAID-0),
- *  which is not supported by the actual SCSI subsystem.
- *  To get the "Array Group" functionality, the Linux MD driver must be used
- *  instead of the DPT "Array Group" feature.
- *
- *  Multiple ISA, EISA and PCI boards can be configured in the same system.
- *  It is suggested to put all the EISA boards on the same IRQ level, all
- *  the PCI  boards on another IRQ level, while ISA boards cannot share
- *  interrupts.
- *
- *  If you configure multiple boards on the same IRQ, the interrupt must
- *  be _level_ triggered (not _edge_ triggered).
- *
- *  This driver detects EATA boards by probes at fixed port addresses,
- *  so no BIOS32 or PCI BIOS support is required.
- *  The suggested way to detect a generic EATA PCI board is to force on it
- *  any unused EISA address, even if there are other controllers on the EISA
- *  bus, or even if you system has no EISA bus at all.
- *  Do not force any ISA address on EATA PCI boards.
- *
- *  If PCI bios support is configured into the kernel, BIOS32 is used to
- *  include in the list of i/o ports to be probed all the PCI SCSI controllers.
- *
- *  Due to a DPT BIOS "feature", it might not be possible to force an EISA
- *  address on more than a single DPT PCI board, so in this case you have to
- *  let the PCI BIOS assign the addresses.
- *
- *  The sequence of detection probes is:
- *
- *  - ISA 0x1F0;
- *  - PCI SCSI controllers (only if BIOS32 is available);
- *  - EISA/PCI 0x1C88 through 0xFC88 (corresponding to EISA slots 1 to 15);
- *  - ISA  0x170, 0x230, 0x330.
- *
- *  The above list of detection probes can be totally replaced by the
- *  boot command line option: "eata=port0,port1,port2,...", where the
- *  port0, port1... arguments are ISA/EISA/PCI addresses to be probed.
- *  For example using "eata=0x7410,0x7450,0x230", the driver probes
- *  only the two PCI addresses 0x7410 and 0x7450 and the ISA address 0x230,
- *  in this order; "eata=0" totally disables this driver.
- *
- *  After the optional list of detection probes, other possible command line
- *  options are:
- *
- *  et:y  force use of extended translation (255 heads, 63 sectors);
- *  et:n  use disk geometry detected by scsicam_bios_param;
- *  rs:y  reverse scan order while detecting PCI boards;
- *  rs:n  use BIOS order while detecting PCI boards;
- *  lc:y  enables linked commands;
- *  lc:n  disables linked commands;
- *  tm:0  disables tagged commands (same as tc:n);
- *  tm:1  use simple queue tags (same as tc:y);
- *  tm:2  use ordered queue tags (same as tc:2);
- *  mq:xx set the max queue depth to the value xx (2 <= xx <= 32).
- *
- *  The default value is: "eata=lc:n,mq:16,tm:0,et:n,rs:n".
- *  An example using the list of detection probes could be:
- *  "eata=0x7410,0x230,lc:y,tm:2,mq:4,et:n".
- *
- *  When loading as a module, parameters can be specified as well.
- *  The above example would be (use 1 in place of y and 0 in place of n):
- *
- *  modprobe eata io_port=0x7410,0x230 linked_comm=1 \
- *                max_queue_depth=4 ext_tran=0 tag_mode=2 \
- *                rev_scan=1
- *
- *  ----------------------------------------------------------------------------
- *  In this implementation, linked commands are designed to work with any DISK
- *  or CD-ROM, since this linking has only the intent of clustering (time-wise)
- *  and reordering by elevator sorting commands directed to each device,
- *  without any relation with the actual SCSI protocol between the controller
- *  and the device.
- *  If Q is the queue depth reported at boot time for each device (also named
- *  cmds/lun) and Q > 2, whenever there is already an active command to the
- *  device all other commands to the same device  (up to Q-1) are kept waiting
- *  in the elevator sorting queue. When the active command completes, the
- *  commands in this queue are sorted by sector address. The sort is chosen
- *  between increasing or decreasing by minimizing the seek distance between
- *  the sector of the commands just completed and the sector of the first
- *  command in the list to be sorted.
- *  Trivial math assures that the unsorted average seek distance when doing
- *  random seeks over S sectors is S/3.
- *  When (Q-1) requests are uniformly distributed over S sectors, the average
- *  distance between two adjacent requests is S/((Q-1) + 1), so the sorted
- *  average seek distance for (Q-1) random requests over S sectors is S/Q.
- *  The elevator sorting hence divides the seek distance by a factor Q/3.
- *  The above pure geometric remarks are valid in all cases and the
- *  driver effectively reduces the seek distance by the predicted factor
- *  when there are Q concurrent read i/o operations on the device, but this
- *  does not necessarily results in a noticeable performance improvement:
- *  your mileage may vary....
- *
- *  Note: command reordering inside a batch of queued commands could cause
- *        wrong results only if there is at least one write request and the
- *        intersection (sector-wise) of all requests is not empty.
- *        When the driver detects a batch including overlapping requests
- *        (a really rare event) strict serial (pid) order is enforced.
- *  ----------------------------------------------------------------------------
- *  The extended translation option (et:y) is useful when using large physical
- *  disks/arrays. It could also be useful when switching between Adaptec boards
- *  and DPT boards without reformatting the disk.
- *  When a boot disk is partitioned with extended translation, in order to
- *  be able to boot it with a DPT board is could be necessary to add to
- *  lilo.conf additional commands as in the following example:
- *
- *  fix-table
- *  disk=/dev/sda bios=0x80 sectors=63 heads=128 cylindres=546
- *
- *  where the above geometry should be replaced with the one reported at
- *  power up by the DPT controller.
- *  ----------------------------------------------------------------------------
- *
- *  The boards are named EATA0, EATA1,... according to the detection order.
- *
- *  In order to support multiple ISA boards in a reliable way,
- *  the driver sets host->wish_block = 1 for all ISA boards.
