- *    seagate.c Copyright (C) 1992, 1993 Drew Eckhardt
- *      low level scsi driver for ST01/ST02, Future Domain TMC-885,
- *      TMC-950 by Drew Eckhardt <drew@colorado.edu>
- *
- *      Note : TMC-880 boards don't work because they have two bits in
- *              the status register flipped, I'll fix this "RSN"
- *	[why do I have strong feeling that above message is from 1993? :-)
- *	        pavel@ucw.cz]
- *
- *      This card does all the I/O via memory mapped I/O, so there is no need
- *      to check or allocate a region of the I/O address space.
- */
-
-/* 1996 - to use new read{b,w,l}, write{b,w,l}, and phys_to_virt
- * macros, replaced assembler routines with C. There's probably a
- * performance hit, but I only have a cdrom and can't tell. Define
- * SEAGATE_USE_ASM if you want the old assembler code -- SJT
- *
- * 1998-jul-29 - created DPRINTK macros and made it work under 
- * linux 2.1.112, simplified some #defines etc. <pavel@ucw.cz>
- *
- * Aug 2000 - aeb - deleted seagate_st0x_biosparam(). It would try to
- * read the physical disk geometry, a bad mistake. Of course it doesn't
- * matter much what geometry one invents, but on large disks it
- * returned 256 (or more) heads, causing all kind of failures.
- * Of course this means that people might see a different geometry now,
- * so boot parameters may be necessary in some cases.

-/*
- * Configuration :
- * To use without BIOS -DOVERRIDE=base_address -DCONTROLLER=FD or SEAGATE
- * -DIRQ will override the default of 5.
- * Note: You can now set these options from the kernel's "command line".
- * The syntax is:
- *
- *     st0x=ADDRESS,IRQ                (for a Seagate controller)
- * or:
- *     tmc8xx=ADDRESS,IRQ              (for a TMC-8xx or TMC-950 controller)
- * eg:
- *     tmc8xx=0xC8000,15
- *
- * will configure the driver for a TMC-8xx style controller using IRQ 15
- * with a base address of 0xC8000.
- *
- * -DARBITRATE 
- *      Will cause the host adapter to arbitrate for the
- *      bus for better SCSI-II compatibility, rather than just
- *      waiting for BUS FREE and then doing its thing.  Should
- *      let us do one command per Lun when I integrate my
- *      reorganization changes into the distribution sources.
- *
- * -DDEBUG=65535
- *      Will activate debug code.
- *
- * -DFAST or -DFAST32 
- *      Will use blind transfers where possible
- *
- * -DPARITY  
- *      This will enable parity.
- *
- * -DSEAGATE_USE_ASM
- *      Will use older seagate assembly code. should be (very small amount)
- *      Faster.
- *
- * -DSLOW_RATE=50
- *      Will allow compatibility with broken devices that don't
- *      handshake fast enough (ie, some CD ROM's) for the Seagate
- *      code.
- *
- *      50 is some number, It will let you specify a default
- *      transfer rate if handshaking isn't working correctly.
- *
- * -DOLDCNTDATASCEME  There is a new sceme to set the CONTROL
- *                    and DATA reigsters which complies more closely
- *                    with the SCSI2 standard. This hopefully eliminates
- *                    the need to swap the order these registers are
- *                    'messed' with. It makes the following two options
- *                    obsolete. To reenable the old sceme define this.
- *
- * The following to options are patches from the SCSI.HOWTO
- *
- * -DSWAPSTAT  This will swap the definitions for STAT_MSG and STAT_CD.
- *
- * -DSWAPCNTDATA  This will swap the order that seagate.c messes with
- *                the CONTROL an DATA registers.

- * Support for broken devices :
- * The Seagate board has a handshaking problem.  Namely, a lack
- * thereof for slow devices.  You can blast 600K/second through
- * it if you are polling for each byte, more if you do a blind
- * transfer.  In the first case, with a fast device, REQ will
- * transition high-low or high-low-high before your loop restarts
- * and you'll have no problems.  In the second case, the board
- * will insert wait states for up to 13.2 usecs for REQ to
- * transition low->high, and everything will work.
- *
- * However, there's nothing in the state machine that says
- * you *HAVE* to see a high-low-high set of transitions before
- * sending the next byte, and slow things like the Trantor CD ROMS
- * will break because of this.
- *
- * So, we need to slow things down, which isn't as simple as it
- * seems.  We can't slow things down period, because then people
- * who don't recompile their kernels will shoot me for ruining
- * their performance.  We need to do it on a case per case basis.
- *
- * The best for performance will be to, only for borken devices
- * (this is stored on a per-target basis in the scsi_devices array)
- *
- * Wait for a low->high transition before continuing with that
- * transfer.  If we timeout, continue anyways.  We don't need
- * a long timeout, because REQ should only be asserted until the
- * corresponding ACK is received and processed.
- *
- * Note that we can't use the system timer for this, because of
- * resolution, and we *really* can't use the timer chip since
- * gettimeofday() and the beeper routines use that.  So,
- * the best thing for us to do will be to calibrate a timing
- * loop in the initialization code using the timer chip before
- * gettimeofday() can screw with it.
