-+ */
-+
-+/*
-+ * Mostly written by Mark Lord <mlord@pobox.com>
-+ * and Gadi Oxman <gadio@netvision.net.il>
-+ * and Andre Hedrick <andre@linux-ide.org>
-+ *
-+ * See linux/MAINTAINERS for address of current maintainer.
-+ *
-+ * This is the multiple IDE interface driver, as evolved from hd.c.
-+ * It supports up to MAX_HWIFS IDE interfaces, on one or more IRQs
-+ * (usually 14 & 15).
-+ * There can be up to two drives per interface, as per the ATA-2 spec.
-+ *
-+ * Primary: ide0, port 0x1f0; major=3; hda is minor=0; hdb is minor=64
-+ * Secondary: ide1, port 0x170; major=22; hdc is minor=0; hdd is minor=64
-+ * Tertiary: ide2, port 0x???; major=33; hde is minor=0; hdf is minor=64
-+ * Quaternary: ide3, port 0x???; major=34; hdg is minor=0; hdh is minor=64
-+ * ...
-+ *
-+ * From hd.c:
-+ * |
-+ * | It traverses the request-list, using interrupts to jump between functions.
-+ * | As nearly all functions can be called within interrupts, we may not sleep.
-+ * | Special care is recommended. Have Fun!
-+ * |
-+ * | modified by Drew Eckhardt to check nr of hd's from the CMOS.
-+ * |
-+ * | Thanks to Branko Lankester, lankeste@fwi.uva.nl, who found a bug
-+ * | in the early extended-partition checks and added DM partitions.
-+ * |
-+ * | Early work on error handling by Mika Liljeberg (liljeber@cs.Helsinki.FI).
-+ * |
-+ * | IRQ-unmask, drive-id, multiple-mode, support for ">16 heads",
-+ * | and general streamlining by Mark Lord (mlord@pobox.com).

-+ * October, 1994 -- Complete line-by-line overhaul for linux 1.1.x, by:
-+ *
-+ * Mark Lord (mlord@pobox.com) (IDE Perf.Pkg)
-+ * Delman Lee (delman@ieee.org) ("Mr. atdisk2")
-+ * Scott Snyder (snyder@fnald0.fnal.gov) (ATAPI IDE cd-rom)
-+ *
-+ * This was a rewrite of just about everything from hd.c, though some original
-+ * code is still sprinkled about. Think of it as a major evolution, with
-+ * inspiration from lots of linux users, esp. hamish@zot.apana.org.au
-+ *
-+ * Version 1.0 ALPHA initial code, primary i/f working okay
-+ * Version 1.3 BETA dual i/f on shared irq tested & working!
-+ * Version 1.4 BETA added auto probing for irq(s)
-+ * Version 1.5 BETA added ALPHA (untested) support for IDE cd-roms,
-+ * ...
-+ * Version 5.50 allow values as small as 20 for idebus=
-+ * Version 5.51 force non io_32bit in drive_cmd_intr()
-+ * change delay_10ms() to delay_50ms() to fix problems
-+ * Version 5.52 fix incorrect invalidation of removable devices
-+ * add "hdx=slow" command line option
-+ * Version 5.60 start to modularize the driver; the disk and ATAPI
-+ * drivers can be compiled as loadable modules.
-+ * move IDE probe code to ide-probe.c
-+ * move IDE disk code to ide-disk.c
-+ * add support for generic IDE device subdrivers
-+ * add m68k code from Geert Uytterhoeven
-+ * probe all interfaces by default
-+ * add ioctl to (re)probe an interface
-+ * Version 6.00 use per device request queues
-+ * attempt to optimize shared hwgroup performance
-+ * add ioctl to manually adjust bandwidth algorithms
-+ * add kerneld support for the probe module
-+ * fix bug in ide_error()
-+ * fix bug in the first ide_get_lock() call for Atari
-+ * don't flush leftover data for ATAPI devices
-+ * Version 6.01 clear hwgroup->active while the hwgroup sleeps
-+ * support HDIO_GETGEO for floppies
-+ * Version 6.02 fix ide_ack_intr() call
-+ * check partition table on floppies
-+ * Version 6.03 handle bad status bit sequencing in ide_wait_stat()
-+ * Version 6.10 deleted old entries from this list of updates
-+ * replaced triton.c with ide-dma.c generic PCI DMA
-+ * added support for BIOS-enabled UltraDMA
-+ * rename all "promise" things to "pdc4030"
-+ * fix EZ-DRIVE handling on small disks
-+ * Version 6.11 fix probe error in ide_scan_devices()
-+ * fix ancient "jiffies" polling bugs
-+ * mask all hwgroup interrupts on each irq entry
-+ * Version 6.12 integrate ioctl and proc interfaces
-+ * fix parsing of "idex=" command line parameter
-+ * Version 6.13 add support for ide4/ide5 courtesy rjones@orchestream.com
-+ * Version 6.14 fixed IRQ sharing among PCI devices
-+ * Version 6.15 added SMP awareness to IDE drivers
-+ * Version 6.16 fixed various bugs; even more SMP friendly
-+ * Version 6.17 fix for newest EZ-Drive problem
-+ * Version 6.18 default unpartitioned-disk translation now "BIOS LBA"
-+ * Version 6.19 Re-design for a UNIFORM driver for all platforms,
-+ * model based on suggestions from Russell King and
-+ * Geert Uytterhoeven
-+ * Promise DC4030VL now supported.
-+ * add support for ide6/ide7
-+ * delay_50ms() changed to ide_delay_50ms() and exported.
-+ * Version 6.20 Added/Fixed Generic ATA-66 support and hwif detection.
-+ * Added hdx=flash to allow for second flash disk
-+ * detection w/o the hang loop.
-+ * Added support for ide8/ide9
-+ * Added idex=ata66 for the quirky chipsets that are
-+ * ATA-66 compliant, but have yet to determine a method
-+ * of verification of the 80c cable presence.
-+ * Specifically Promise's PDC20262 chipset.
-+ * Version 6.21 Fixing/Fixed SMP spinlock issue with insight from an old
-+ * hat that clarified original low level driver design.
-+ * Version 6.30 Added SMP support; fixed multmode issues. -ml
-+ * Version 6.31 Debug Share INTR's and request queue streaming
-+ * Native ATA-100 support
-+ * Prep for Cascades Project
-+ * Version 7.00alpha First named revision of ide rearrange
-+ *
-+ * Some additional driver compile-time options are in ./include/linux/ide.h
-+ *
-+ * To do, in likely order of completion:
-+ * - modify kernel to obtain BIOS geometry for drives on 2nd/3rd/4th i/f
