Subject: [PATCH] scsi: eata: drop EATA and EATA-PIO drivers
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]
- * mq:xx max_queue_depth=xx
- * tm:[0|1|2] tag_mode=[0|1|2]

- * ip:[y|n] isa_probe=[1|0]
- * ep:[y|n] eisa_probe=[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:
- * modprobe eata io_port=0x7410,0x230 linked_comm=1 tag_mode=0 \
- * 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
- * ep:[y|n] eisa_probe=[1|0] CONFIG_EISA 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
- * + Use the dynamic DMA mapping API.
- *
- * 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

- * + 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.

- * support).
- *
- * 09 Jul 1996 rev. 2.11 for linux 2.0.4
- * Number of internal retries is now limited.
- *
- * 16 Apr 1996 rev. 2.10 for linux 1.3.90
- * New argument "reset_flags" to the reset routine.
- *
- * 6 Jul 1995 rev. 2.01 for linux 1.3.7

- * Now DEBUG_RESET is disabled by default.
- * Register a board even if it does not assert DMA protocol support
- * (DPT SK2011B does not report correctly the dmasup bit).
- *
- * 9 Feb 1995 rev. 1.16 for linux 1.1.90
- * Use host->wish_block instead of host->block.
- * New list of Data Out SCSI commands.

- * 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.
