-	  If you say Y here, your kernel will be able to manage low cost mass
-	  storage units such as ATA/(E)IDE and ATAPI units. The most common
-	  cases are IDE hard drives and ATAPI CD-ROM drives.
-
-	  If your system is pure SCSI and doesn't use these interfaces, you
-	  can say N here.
-
-	  Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
-	  for mass storage units such as hard disks. It was designed by
-	  Western Digital and Compaq Computer in 1984. It was then named
-	  ST506. Quite a number of disks use the IDE interface.
-
-	  AT Attachment (ATA) is the superset of the IDE specifications.
-	  ST506 was also called ATA-1.
-
-	  Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
-	  ATA-3. It provides support for larger disks (up to 8.4GB by means of
-	  the LBA standard), more disks (4 instead of 2) and for other mass
-	  storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
-	  ATA-4 and provides faster (and more CPU friendly) transfer modes
-	  than previous PIO (Programmed processor Input/Output) from previous
-	  ATA/IDE standards by means of fast DMA controllers.
-
-	  ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
-	  CD-ROM drives, similar in many respects to the SCSI protocol.
-
-	  SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
-	  designed in order to prevent data corruption and disk crash by
-	  detecting pre hardware failure conditions (heat, access time, and
-	  the like...). Disks built since June 1995 may follow this standard.
-	  The kernel itself doesn't manage this; however there are quite a
-	  number of user programs such as smart that can query the status of
-	  SMART parameters from disk drives.
+	  If you say Y here, your kernel will be able to manage ATA/(E)IDE and
+	  ATAPI units. The most common cases are IDE hard drives and ATAPI
+	  CD-ROM drives.
+
+	  This subsystem is currently in maintenance mode with only bug fix
+	  changes applied. Users of ATA hardware are encouraged to migrate to
+	  the newer ATA subsystem ("Serial ATA (prod) and Parallel ATA
+	  (experimental) drivers") which is more actively maintained.
 
 	  To compile this driver as a module, choose M here: the

- *
- *  Version 0.01        Initial version hacked out of ide.c
- *
- *  Version 0.02        Added support for PIO modes, auto-tune
- *
- *  Version 0.03        Some cleanups
- *
- *  Version 0.05        PIO mode cycle timings auto-tune using bus-speed
- *
- *  Version 0.06        Prefetch mode now defaults no OFF. To set
- *                      prefetch mode OFF/ON use "hdparm -p8/-p9".
- *                      Unmask irq is disabled when prefetch mode
- *                      is enabled.
- *
- *  Version 0.07        Trying to fix CD-ROM detection problem.
- *                      "Prefetch" mode bit OFF for ide disks and
- *                      ON for anything else.
- *
- *  Version 0.08        Need to force prefetch for CDs and other non-disk
- *                      devices. (not sure which devices exactly need
- *                      prefetch)
- *
  *  HT-6560B EIDE-controller support
  *  To activate controller support use kernel parameter "ide0=ht6560b".
  *  Use hdparm utility to enable PIO mode support.

- * Issue a new request to a drive from hwgroup
- * Caller must have already done spin_lock_irqsave(&ide_lock, ..);
- *
- * A hwgroup is a serialized group of IDE interfaces.  Usually there is
- * exactly one hwif (interface) per hwgroup, but buggy controllers (eg. CMD640)
- * may have both interfaces in a single hwgroup to "serialize" access.
- * Or possibly multiple ISA interfaces can share a common IRQ by being grouped
- * together into one hwgroup for serialized access.
- *
- * Note also that several hwgroups can end up sharing a single IRQ,
- * possibly along with many other devices.  This is especially common in
- * PCI-based systems with off-board IDE controller cards.
- *
- * The IDE driver uses the single global ide_lock spinlock to protect
- * access to the request queues, and to protect the hwgroup->busy flag.
- *
- * The first thread into the driver for a particular hwgroup sets the
- * hwgroup->busy flag to indicate that this hwgroup is now active,
- * and then initiates processing of the top request from the request queue.
- *
- * Other threads attempting entry notice the busy setting, and will simply
- * queue their new requests and exit immediately.  Note that hwgroup->busy
- * remains set even when the driver is merely awaiting the next interrupt.
- * Thus, the meaning is "this hwgroup is busy processing a request".
- *
- * When processing of a request completes, the completing thread or IRQ-handler
- * will start the next request from the queue.  If no more work remains,
- * the driver will clear the hwgroup->busy flag and exit.
- *
- * The ide_lock (spinlock) is used to protect all access to the
- * hwgroup->busy flag, but is otherwise not needed for most processing in
- * the driver.  This makes the driver much more friendlier to shared IRQs
- * than previous designs, while remaining 100% (?) SMP safe and capable.

- *	Locking:

- *	The drive present/vanishing is not yet properly locked
- *	Take care with the callbacks. These have been split to avoid
- *	deadlocking the IDE layer. The shutdown callback is called

- *	caller to be sure there is no pending I/O here, and that
- *	the interface will not be reopened (present/vanishing locking
- *	isn't yet done BTW). After we commit to the final kill we
- *	call the cleanup callback with the ide locks held.
- *
- *	Unregister restores the hwif structures to the default state.

- * CYPRESS CY82C693 chipset IDE controller
- *
- * The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards.
- * Writing the driver was quite simple, since most of the job is
- * done by the generic pci-ide support. 
- * The hard part was finding the CY82C693's datasheet on Cypress's
- * web page :-(. But Altavista solved this problem :-).
- *
- *
- * Notes:
- * - I recently got a 16.8G IBM DTTA, so I was able to test it with
- *   a large and fast disk - the results look great, so I'd say the
- *   driver is working fine :-)
- *   hdparm -t reports 8.17 MB/sec at about 6% CPU usage for the DTTA 
- * - this is my first linux driver, so there's probably a lot  of room 
- *   for optimizations and bug fixing, so feel free to do it.
- * - use idebus=xx parameter to set PCI bus speed - needed to calc
- *   timings for PIO modes (default will be 40)
- * - if using PIO mode it's a good idea to set the PIO mode and 
- *   32-bit I/O support (if possible), e.g. hdparm -p2 -c1 /dev/hda
- * - I had some problems with my IBM DHEA with PIO modes < 2
- *   (lost interrupts) ?????
- * - first tests with DMA look okay, they seem to work, but there is a
- *   problem with sound - the BusMaster IDE TimeOut should fixed this
- *
- * Ancient History:
- * AMH@1999-08-24: v0.34 init_cy82c693_chip moved to pci_init_cy82c693
- * ASK@1999-01-23: v0.33 made a few minor code clean ups
- *                       removed DMA clock speed setting by default
- *                       added boot message
- * ASK@1998-11-01: v0.32 added support to set BusMaster IDE TimeOut
- *                       added support to set DMA Controller Clock Speed
- * ASK@1998-10-31: v0.31 fixed problem with setting to high DMA modes
- *                       on some drives.
- * ASK@1998-10-29: v0.3 added support to set DMA modes
- * ASK@1998-10-28: v0.2 added support to set PIO modes
- * ASK@1998-10-27: v0.1 first version - chipset detection

-/*
- * Authors:
- * Jaromir Koutek <miri@punknet.cz>,
- * Jan Harkes <jaharkes@cwi.nl>,
- * Mark Lord <mlord@pobox.com>
- * Some parts of code are from ali14xx.c and from rz1000.c.
- *
- * OPTi is trademark of OPTi, Octek is trademark of Octek.
- *
- * I used docs from OPTi databook, from ftp.opti.com, file 9123-0002.ps
- * and disassembled/traced setupvic.exe (DOS program).
- * It increases kernel code about 2 kB.
- * I don't have this card no more, but I hope I can get some in case
- * of needed development.
- * My card is Octek PIDE 1.01 (on card) or OPTiViC (program).
- * It has a place for a secondary connector in circuit, but nothing
- * is there. Also BIOS says no address for
- * secondary controller (see bellow in ide_init_opti621).
- * I've only tested this on my system, which only has one disk.
- * It's Western Digital WDAC2850, with PIO mode 3. The PCI bus
- * is at 20 MHz (I have DX2/80, I tried PCI at 40, but I got random
- * lockups). I tried the OCTEK double speed CD-ROM and
- * it does not work! But I can't boot DOS also, so it's probably
- * hardware fault. I have connected Conner 80MB, the Seagate 850MB (no
- * problems) and Seagate 1GB (as slave, WD as master). My experiences
- * with the third, 1GB drive: I got 3MB/s (hdparm), but sometimes
- * it slows to about 100kB/s! I don't know why and I have
- * not this drive now, so I can't try it again.
- * I write this driver because I lost the paper ("manual") with
- * settings of jumpers on the card and I have to boot Linux with
- * Loadlin except LILO, cause I have to run the setupvic.exe program
- * already or I get disk errors (my test: rpm -Vf
- * /usr/X11R6/bin/XF86_SVGA - or any big file).
- * Some numbers from hdparm -t /dev/hda:
- * Timing buffer-cache reads:   32 MB in  3.02 seconds =10.60 MB/sec
- * Timing buffered disk reads:  16 MB in  5.52 seconds = 2.90 MB/sec
- * I have 4 Megs/s before, but I don't know why (maybe changes
- * in hdparm test).
- * After release of 0.1, I got some successful reports, so it might work.
- *
- * The main problem with OPTi is that some timings for master
- * and slave must be the same. For example, if you have master
- * PIO 3 and slave PIO 0, driver have to set some timings of
- * master for PIO 0. Second problem is that opti621_set_pio_mode
- * got only one drive to set, but have to set both drives.
- * This is solved in compute_pios. If you don't set
- * the second drive, compute_pios use ide_get_best_pio_mode
- * for autoselect mode (you can change it to PIO 0, if you want).
- * If you then set the second drive to another PIO, the old value
- * (automatically selected) will be overrided by yours.
- * There is a 25/33MHz switch in configuration
- * register, but driver is written for use at any frequency which get
- * (use idebus=xx to select PCI bus speed).
- *
- * Version 0.1, Nov 8, 1996
- * by Jaromir Koutek, for 2.1.8. 
- * Initial version of driver.
- * 
- * Version 0.2
- * Number 0.2 skipped.
- *
- * Version 0.3, Nov 29, 1997
- * by Mark Lord (probably), for 2.1.68
- * Updates for use with new IDE block driver.
- *
- * Version 0.4, Dec 14, 1997
- * by Jan Harkes
- * Fixed some errors and cleaned the code.
- *
- * Version 0.5, Jan 2, 1998
- * by Jaromir Koutek
- * Updates for use with (again) new IDE block driver.
- * Update of documentation.
- * 
- * Version 0.6, Jan 2, 1999
- * by Jaromir Koutek
- * Reversed to version 0.3 of the driver, because
- * 0.5 doesn't work.

- *	If you are using Marvell SATA-IDE adapters with Maxtor drives
- *	ensure the system is set up for ATA100/UDMA5 not UDMA6.
- *
- *	If you are using WD drives with SATA bridges you must set the
- *	drive to "Single". "Master" will hang
- *
- *	If you have strange problems with nVidia chipset systems please
- *	see the SI support documentation and update your system BIOS
- *	if necessary
- *
- *  The Dell DRAC4 has some interesting features including effectively hot
- *  unplugging/replugging the virtual CD interface when the DRAC is reset.
- *  This often causes drivers/ide/siimage to panic but is ok with the rather
- *  smarter code in libata.
