+/*
+ *  linux/kernel/arch/arm/drivers/block/fd1772.c
+ *  Based on ataflop.c in the m68k Linux
+ *  Copyright (C) 1993  Greg Harp
+ *  Atari Support by Bjoern Brauel, Roman Hodek
+ *  Archimedes Support by Dave Gilbert (gilbertd@cs.man.ac.uk)
+ *
+ *  Big cleanup Sep 11..14 1994 Roman Hodek:
+ *   - Driver now works interrupt driven
+ *   - Support for two drives; should work, but I cannot test that :-(
+ *   - Reading is done in whole tracks and buffered to speed up things
+ *   - Disk change detection and drive deselecting after motor-off
+ *     similar to TOS
+ *   - Autodetection of disk format (DD/HD); untested yet, because I
+ *     don't have an HD drive :-(
+ *
+ *  Fixes Nov 13 1994 Martin Schaller:
+ *   - Autodetection works now
+ *   - Support for 5 1/4" disks
+ *   - Removed drive type (unknown on atari)
+ *   - Do seeks with 8 Mhz
+ *
+ *  Changes by Andreas Schwab:
+ *   - After errors in multiple read mode try again reading single sectors
+ *  (Feb 1995):
+ *   - Clean up error handling
+ *   - Set blk_size for proper size checking
+ *   - Initialize track register when testing presence of floppy
+ *   - Implement some ioctl's
+ *
+ *  Changes by Torsten Lang:
+ *   - When probing the floppies we should add the FDC1772CMDADD_H flag since
+ *     the FDC1772 will otherwise wait forever when no disk is inserted...
+ *
+ *  Things left to do:
+ *   - Formatting
+ *   - Maybe a better strategy for disk change detection (does anyone
+ *     know one?)
+ *   - There are some strange problems left: The strangest one is
+ *     that, at least on my TT (4+4MB), the first 2 Bytes of the last
+ *     page of the TT-Ram (!) change their contents (some bits get
+ *     set) while a floppy DMA is going on. But there are no accesses
+ *     to these memory locations from the kernel... (I tested that by
+ *     making the page read-only). I cannot explain what's going on...
+ *   - Sometimes the drive-change-detection stops to work. The
+ *     function is still called, but the WP bit always reads as 0...
+ *     Maybe a problem with the status reg mode or a timing problem.
+ *     Note 10/12/94: The change detection now seems to work reliably.
+ *     There is no proof, but I've seen no hang for a long time...
+ *
+ * ARCHIMEDES changes: (gilbertd@cs.man.ac.uk)
+ *     26/12/95 - Changed all names starting with FDC to FDC1772
+ *                Removed all references to clock speed of FDC - we're stuck with 8MHz
+ *                Modified disk_type structure to remove HD formats
+ *
+ *      7/ 1/96 - Wrote FIQ code, removed most remaining atariisms
+ *
+ *     13/ 1/96 - Well I think its read a single sector; but there is a problem
+ *                fd_rwsec_done which is called in FIQ mode starts another transfer
+ *                off (in fd_rwsec) while still in FIQ mode.  Because its still in
+ *                FIQ mode it can't service the DMA and loses data. So need to
+ *                heavily restructure.
+ *     14/ 1/96 - Found that the definitions of the register numbers of the
+ *                FDC were multiplied by 2 in the header for the 16bit words
+ *                of the atari so half the writes were going in the wrong place.
+ *                Also realised that the FIQ entry didn't make any attempt to
+ *                preserve registers or return correctly; now in assembler.
+ *
+ *     11/ 2/96 - Hmm - doesn't work on real machine.  Auto detect doesn't
+ *                and hacking that past seems to wait forever - check motor
+ *                being turned on.
+ *
+ *     17/ 2/96 - still having problems - forcing track to -1 when selecting
+ *                new drives seems to allow it to read first few sectors
+ *                but then we get solid hangs at apparently random places
+ *                which change depending what is happening.
+ *
+ *      9/ 3/96 - Fiddled a lot of stuff around to move to kernel 1.3.35
+ *                A lot of fiddling in DMA stuff. Having problems with it
+ *                constnatly thinking its timeing out. Ah - its timeout
+ *                was set to (6*HZ) rather than jiffies+(6*HZ).  Now giving
+ *                duff data!
+ *
+ *      5/ 4/96 - Made it use the new IOC_ macros rather than *ioc
+ *                Hmm - giving unexpected FIQ and then timeouts
+ *     18/ 8/96 - Ran through indent -kr -i8
+ *                Some changes to disc change detect; don't know how well it
+ *                works.
+ *     24/ 8/96 - Put all the track buffering code back in from the atari
+ *                code - I wonder if it will still work... No :-)
+ *                Still works if I turn off track buffering.
+ *     25/ 8/96 - Changed the timer expires that I'd added back to be 
+ *                jiffies + ....; and it all sprang to life! Got 2.8K/sec
+ *                off a cp -r of a 679K disc (showed 94% cpu usage!)
+ *                (PC gets 14.3K/sec - 0% CPU!) Hmm - hard drive corrupt!
+ *                Also perhaps that compile was with cache off.
+ *                changed cli in fd_readtrack_check to cliIF
+ *                changed vmallocs to kmalloc (whats the difference!!)
+ *                Removed the busy wait loop in do_fd_request and replaced
+ *                by a routine on tq_immediate; only 11% cpu on a dd off the
+ *                raw disc - but the speed is the same.
+ *	1/ 9/96 - Idea (failed!) - set the 'disable spin-up seqeunce'
+ *		  when we read the track if we know the motor is on; didn't
+ *		  help - perhaps we have to do it in stepping as well.
+ *		  Nope. Still doesn't help.
+ *		  Hmm - what seems to be happening is that fd_readtrack_check
+ *		  is never getting called. Its job is to terminate the read
+ *		  just after we think we should have got the data; otherwise
+ *		  the fdc takes 1 second to timeout; which is what's happening
+ *		  Now I can see 'readtrack_timer' being set (which should do the
+ *		  call); but it never seems to be called - hmm!
+ *		  OK - I've moved the check to my tq_immediate code -
+ *		  and it WORKS! 13.95K/second at 19% CPU.
+ *		  I wish I knew why that timer didn't work.....
+ *
+ *     16/11/96 - Fiddled and frigged for 2.0.18

+/*
+ * Change list:
+ *
+ *  3/2/96:DAG: Started a change list :-)
+ *              Set the hardsect_size pointers up since we are running 256 byte
+ *                sectors
+ *              Added DMA code, put it into the rw_intr
+ *              Moved RCAL out of generic interrupt code - don't want to do it
+ *                while DMA'ing - its now in individual handlers.
+ *              Took interrupt handlers off task queue lists and called
+ *                directly - not sure of implications.
+ *
+ * 18/2/96:DAG: Well its reading OK I think, well enough for image file code
+ *              to find the image file; but now I've discovered that I actually
+ *              have to put some code in for image files.
+ *
+ *              Added stuff for image files; seems to work, but I've not
+ *              got a multisegment image file (I don't think!).
+ *              Put in a hack (yep a real hack) for multiple cylinder reads.
+ *              Not convinced its working.
+ *
+ *  5/4/96:DAG: Added asm/hardware.h and use IOC_ macros
+ *              Rewrote dma code in mfm.S (again!) - now takes a word at a time
+ *              from main RAM for speed; still doesn't feel speedy!
+ *
+ * 20/4/96:DAG: After rewriting mfm.S a heck of a lot of times and speeding
+ *              things up, I've finally figured out why its so damn slow.
+ *              Linux is only reading a block at a time, and so you never
+ *              get more than 1K per disc revoloution ~=60K/second.
+ *
+ * 27/4/96:DAG: On Russell's advice I change ll_rw_blk.c to ask it to
+ *              join adjacent blocks together. Everything falls flat on its
+ *              face.
+ *              Four hours of debugging later; I hadn't realised that
+ *              ll_rw_blk would be so generous as to join blocks whose
+ *              results aren't going into consecutive buffers.
+ * 
+ *              OK; severe rehacking of mfm_rw_interrupt; now end_request's
+ *              as soon as its DMA'd each request.  Odd thing is that
+ *              we are sometimes getting interrupts where we are not transferring
+ *              any data; why? Is that what happens when you miss? I doubt
+ *              it; are we too fast? No - its just at command ends. Got 240K/s
+ *              better than before, but RiscOS hits 480K/s
+ *
+ * 25/6/96:RMK: Fixed init code to allow the MFM podule to work.  Increased the
+ *              number of errors for my Miniscribe drive (8425).
+ *
+ * 30/6/96:DAG: Russell suggested that a check drive 0 might turn the LEDs off
+ *              - so in request_done just before it clears Busy it sends a
+ *              check drive 0 - and the LEDs go off!!!!
+ *
+ *              Added test for mainboard controller. - Removes need for separate
+ *              define.
+ *
+ * 13/7/96:DAG: Changed hardware sectore size to 512 in attempt to make
+ *              IM drivers work.
+ * 21/7/96:DAG: Took out old image file stuff (accessing it now produces an IO
+ *              error.)
+ *
+ * 17/8/96:DAG: Ran through indent -kr -i8; evil - all my nice 2 character indents
+ *              gone :-( Hand modified afterwards.
+ *		Took out last remains of the older image map system.
+ *
+ * 22/9/96:DAG:	Changed mfm.S so it will carry on DMA'ing til; BSY is dropped
+ *		Changed mfm_rw_intr so that it doesn't follow the error
+ *		code until BSY is dropped. Nope - still broke. Problem
+ *		may revolve around when it reads the results for the error
+ *		number?
+ *
+ *16/11/96:DAG:	Modified for 2.0.18; request_irq changed
+ *
+ *17/12/96:RMK: Various cleanups, reorganisation, and the changes for new IO system.
+ *		Improved probe for onboard MFM chip - it was hanging on my A5k.
+ *		Added autodetect CHS code such that we don't rely on the presence
+ *		of an ADFS boot block.  Added ioport resource manager calls so
+ *		that we don't clash with already-running hardware (eg. RiscPC Ether
+ *		card slots if someone tries this)!
+ *
+ * 17/1/97:RMK:	Upgraded to 2.1 kernels.
+ */
+
+/*
+ * Possible enhancements:
+ *  Multi-thread the code so that it is possible that while one drive
+ *  is seeking, the other one can be reading data/seeking as well.
+ *  This would be a performance boost with dual drive systems.

+ * linux/drivers/net/ether3.c
+ *
+ * SEEQ nq8005 ethernet driver for Acorn/ANT Ether3 card
+ *  for Acorn machines
+ *
+ * By Russell King, with some suggestions from borris@ant.co.uk
+ *
+ * Changelog:
+ * 1.04 RMK     29/02/1996      Won't pass packets that are from our ethernet
+ *                              address up to the higher levels - they're
+ *                              silently ignored.  I/F can now be put into
+ *                              multicast mode.  Receiver routine optimised.
+ * 1.05 RMK     30/02/1996      Now claims interrupt at open when part of
+ *                              the kernel rather than when a module.
+ * 1.06 RMK     02/03/1996      Various code cleanups
+ * 1.07 RMK     13/10/1996      Optimised interrupt routine and transmit
+ *                              routines.
+ * 1.08 RMK     14/10/1996      Fixed problem with too many packets,
+ *                              prevented the kernel message about dropped
+ *                              packets appearing too many times a second.
+ *                              Now does not disable all IRQs, only the IRQ
+ *                              used by this card.
+ * 1.09 RMK     10/11/1996      Only enables TX irq when buffer space is low,
+ *                              but we still service the TX queue if we get a
+ *                              RX interrupt.
+ * 1.10 RMK     15/07/1997      Fixed autoprobing of NQ8004.
+ * 1.11 RMK     16/11/1997      Fixed autoprobing of NQ8005A.
+ * 1.12 RMK     31/12/1997      Removed reference to dev_tint for Linux 2.1.
+ *
+ * TODO:
+ *  When we detect a fatal error on the interface, we should restart it.

+/*
+ * linux/arch/arm/drivers/scsi/acornscsi.c
+ *
+ *  Acorn SCSI 3 driver
+ *  By R.M.King.
+ *
+ * Abandoned using the Select and Transfer command since there were
+ * some nasty races between our software and the target devices that
+ * were not easy to solve, and the device errata had a lot of entries
+ * for this command, some of them quite nasty...
+ *
+ * Changelog:
+ *  26-Sep-1997	RMK	Re-jigged to use the queue module.
+ *			Re-coded state machine to be based on driver
+ *			state not scsi state.  Should be easier to debug.
+ *			Added acornscsi_release to clean up properly.
+ *			Updated proc/scsi reporting.
+ *  05-Oct-1997	RMK	Implemented writing to SCSI devices.
+ *  06-Oct-1997	RMK	Corrected small (non-serious) bug with the connect/
+ *			reconnect race condition causing a warning message.
+ *  12-Oct-1997	RMK	Added catch for re-entering interrupt routine.
+ *  15-Oct-1997	RMK	Improved handling of commands.

+ * tagging device reconnects???
+ *
+ * You can tell if you have a device that supports tagged queueing my
+ * cating (eg) /proc/scsi/acornscsi/0 and see if the SCSI revision is reported
+ * as '2 TAG'.
+ *
+ * Also note that CONFIG_SCSI_ACORNSCSI_TAGGED_QUEUE is normally set in the config
+ * scripts, but disabled here.  Once debugged, remove the #undef, otherwise to debug,
+ * comment out the undef.

+/* 	smc-ultra32.c: An SMC Ultra32 EISA ethernet driver for linux.
+
+Sources:
+
+	This driver is based on (cloned from) the ISA SMC Ultra driver
+	written by Donald Becker. Modifications to support the EISA
+	version of the card by Paul Gortmaker and Leonard N. Zubkoff.
+
+	This software may be used and distributed according to the terms
+	of the GNU Public License, incorporated herein by reference.
+
+Theory of Operation:
+
+	The SMC Ultra32C card uses the SMC 83c790 chip which is also
+	found on the ISA SMC Ultra cards. It has a shared memory mode of
+	operation that makes it similar to the ISA version of the card.
+	The main difference is that the EISA card has 32KB of RAM, but
+	only an 8KB window into that memory. The EISA card also can be
+	set for a bus-mastering mode of operation via the ECU, but that
+	is not (and probably will never be) supported by this driver.
+	The ECU should be run to enable shared memory and to disable the
+	bus-mastering feature for use with linux.
+
+	By programming the 8390 to use only 8KB RAM, the modifications
+	to the ISA driver can be limited to the probe and initialization
+	code. This allows easy integration of EISA support into the ISA
+	driver. However, the driver development kit from SMC provided the
+	register information for sliding the 8KB window, and hence the 8390
+	is programmed to use the full 32KB RAM.
+
+	Unfortunately this required code changes outside the probe/init
+	routines, and thus we decided to separate the EISA driver from
+	the ISA one. In this way, ISA users don't end up with a larger
+	driver due to the EISA code, and EISA users don't end up with a
+	larger driver due to the ISA EtherEZ PIO code. The driver is
+	similar to the 3c503/16 driver, in that the window must be set
+	back to the 1st 8KB of space for access to the two 8390 Tx slots.
+
+	In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to
+	be a limiting factor, since the EISA bus could get packets off
+	the card fast enough, but having the use of lots of RAM as Rx
+	space is extra insurance if interrupt latencies become excessive.
