-Sat Jul 24  12:00 1999 Gerard Roudier (groudier@club-internet.fr)
-	* version sym53c8xx-1.3g
-	- merge of driver 1.3f with linux-2.2.11-pre3
-	- remove the broken testing of the chip being connected to SCSI 
-	  from the SCSI interrupt handling code.   
+Wed Jul 26 23:30 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.7.1
+	- Provide OpenFirmare path through the proc FS on PPC.
+	- Download of on-chip SRAM using memcpy_toio() doesn't work 
+	  on PPC. Restore previous method (MEMORY MOVE from SCRIPTS).
+	- Remove trailing argument #2 from a couple of #undefs.

-	* version sym53c8xx-1.3f
+Sun Jul 09 16:30 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.7.0
+	- Remove the PROFILE C and SCRIPTS code.
+	  This facility was not this useful and thus was not longer 
+	  desirable given the increasing complexity of the driver code.
+	- Merges from FreeBSD sym-1.6.2 driver:
+	  * Clarify memory barriers needed by the driver for architectures 
+	    that implement a weak memory ordering.
+	  * Simpler handling of illegal phases and data overrun from 
+	    SCRIPTS. These errors are now immediately reported to 
+	    the C code by an interrupt.
+	  * Sync the residual handling code with sym-1.6.2 and now 
+	    report `resid' to user for linux version >= 2.3.99 
+	- General cleanup:
+	  Move definitions for barriers and IO/MMIO operations to the 
+	  sym53c8xx_defs.h header files. They are now shared by the 
+	  both drivers.
+	  Remove unused options that claimed to optimize for the 896.
+	  If fact, they were not this clever. :)
+	  Use SCSI_NCR_IOMAPPED instead of NCR_IOMAPPED.
+	  Remove a couple of unused fields from data structures.
+
+Thu May 11 12:40 2000 Pam Delaney (pam.delaney@lsil.com)
+	* version sym53c8xx-1.6b
+	- Merged version.
+
+Mon Apr 24 12:00 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5m
+	- Return value 1 (instead of 0) from the driver setup routine.
+	- Donnot enable PCI DAC cycles. This just broke support for 
+	  SYM534C896 on sparc64. Problem fixed by David S. Miller.
+
+Fri Apr 14 9:00 2000 Pam Delaney (pam.delaney@lsil.com)
+	* version sym53c8xx-1.6b-9
+	- Added 53C1010_66 support.
+	- Small fix to integrity checking code.
+	- Removed requirement for integrity checking if want to run
+	  at ultra 3.
+ 
+Sat Apr 1  12:00 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5l
+	- Tiny change for __sparc__ appeared in 2.3.99-pre4.1 that 
+	  applies to cache line size (? Probably from David S Miller).
+	- Make sure no data transfer will happen for Scsi_Cmnd requests 
+	  that supply SCSI_DATA_NONE direction (this avoids some BUG() 
+	  statement in the PCI code when a data buffer is also supplied).
+
+Sat Mar 11 12:00 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.6b-5
+	- Test against expected data transfer direction from SCRIPTS.
+	- Add support for the new dynamic dma mapping kernel interface.
+	  Requires Linux-2.3.47 (tested with pre-2.3.47-6).
+	  Many thanks to David S. Miller for his preliminary changes 
+	  that have been useful guidelines.
+	- Get data transfer direction from the scsi command structure 
+	  (Scsi_Cmnd) with kernels that provide this information.
+
+Mon Mar  6 23:30 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5k
+	- Test against expected data transfer direction from SCRIPTS.
+	- Revert the change in 'ncr_flush_done_cmds()' but unmap the 
+	  scsi dma buffer prior to queueing the command to our done 
+	  list.
+	- Miscellaneous (minor) fixes in the code added in driver 
+	  version 1.5j.
+
+Mon Feb 14 4:00 2000 Pam Delaney (pam.delaney@lsil.com)
+ 	* version sym53c8xx-pre-1.6b-2.
+	- Updated the SCRIPTS error handling of the SWIDE
+	  condition - to remove any reads of the sbdl
+	  register. Changes needed because the 896 and 1010
+	  chips will check parity in some special circumstances.
+	  This will cause a parity error interrupt if not in
+	  data phase.  Changes based on those made in the
+	  FreeBSD driver version 1.3.2.
+
+Sun Feb 20 11:00 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5j
+	- Add support for the new dynamic dma mapping kernel interface.
+	  Requires Linux-2.3.47 (tested with pre-2.3.47-6).
+	  Many thanks to David S. Miller for his preliminary changes 
+	  that have been useful guidelines, for having reviewed the 
+	  code and having tested this driver version on Ultra-Sparc.
+	- 2 tiny bugs fixed in the PCI wrapper that provides support 
+	  for early kernels without pci device structure.
+	- Get data transfer direction from the scsi command structure 
+	  (Scsi_Cmnd) with kernels that provide this information.
+	- Fix an old bug that only affected 896 rev. 1 when driver 
+	  profile support option was set in kernel configuration.
+
+Fri Jan 14 14:00 2000 Pam Delaney (pam.delaney@lsil.com)
+ 	* version sym53c8xx-pre-1.6b-1.
+	- Merge parallel driver series 1.61 and 1.5e 
+
+Tue Jan 11 14:00 2000 Pam Delaney (pam.delaney@lsil.com)
+	* version sym53c8xx-1.61
+	- Added support for mounting disks on wide-narrow-wide
+	  scsi configurations. 
+	- Modified offset to be a maximum of 31 in ST mode, 
+	  62 in DT mode.
+	- Based off of 1.60
+
+Mon Jan 10 10:00 2000 Pam Delaney (pam.delaney@lsil.com)
+	* version sym53c8xx-1.60
+	- Added capability to use the integrity checking code
+	  in the kernel (optional).
+	-  Added PPR negotiation.
+	- Added support for 53C1010 Ultra 3 part.
+	- Based off of 1.5f
+
+Sat Jan 8  22:00 2000 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5h
+	- Add year 2000 copyright.
+	- Display correctly bus signals when bus is detected wrong.
+	- Some fix for Sparc from DSM that went directly to kernel tree.
+
+Mon Dec 6  22:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5g
+	- Change messages written by the driver at initialisation and 
+	  through the /proc FS (rather cosmetic changes that consist in
+	  printing out the PCI bus number and PCI device/function).
+	- Ensure the SCRIPTS processor is stopped while calibrating the 
+	  SCSI clock (the initialisation code has been a bit reworked).
+	  Change moved to the FreeBSD sym_hipd driver).
+	- Some fixes in the MODIFY_DP/IGN_RESIDUE code and residual 
+	  calculation (moved from FreeBSD sym_hipd driver).
+	- Add NVRAM support for Tekram boards that use 24C16 EEPROM.
+	  Code moved from the FreeBSD sym_hipd driver, since it has 
+	  been that one that got this feature first.
+	- Definitely disable overlapped PCI arbitration for all dual 
+	  function chips, since I cannot make sure for what chip revisions 
+	  it is actually safe.
+	- Add support for the SYM53C1510D (also for ncr53c8xx).
+	- Fix up properly the PCI latency timer when needed or asked for.
+	- Get rid of the old PCI bios interface, but preserve kernel 2.0 
+	  compatibility from a simple wrapper.
+	- Update the poor Tekram sync factor table.
+	- Fix in a tiny 'printk' bug that may oops in case of extended 
+	  errors (unrecovered parity error, data overrun, etc ...)
+	  (Sent by Pamela Delaney from LSILOGIC)
+	- Remove the compilation condition about having to acquire the 
+	  io_request_lock since it seems to be a definite feature now.:)
+	- Change get_pages by GetPages since Linux >= 2.3.27 now wants 
+	  get_pages to ever be used as a kernel symbol (from 2.3.27).
+	- proc_dir structure no longer needed for kernel >= 2.3.27.
+
+Sun Oct  3  19:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5f
+	- Change the way the driver checks the PCI clock frequency, so 
+	  that overclocked PCI BUS up to 48 MHz will not be refused.
+	  The more the BUS is overclocked, the less the driver will 
+	  guarantee that its measure of the SCSI clock is correct.
+	- Backport some minor improvements of SCRIPTS from the sym_hipd 
+	  driver.
+	- Backport the code rewrite of the START QUEUE dequeuing (on 
+	  bad scsi status received) from the sym_hipd driver.
+
+Sat Sep 11  11:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5e
+	- New linux-2.3.13 __setup scheme support added.
+	- Cleanup of the extended error status handling:
+	  Use 1 bit per error type.
+	- Also save the extended error status prior to auto-sense.
+	- Add the FE_DIFF chip feature bit to indicate support of 
+	  diff probing from GPIO3 (825/825A/876/875).
+	- Remove the quirk handling that has been useless since day one.
+	- Work-around PCI chips being reported twice on some platforms.
+	- Add some redundant PCI reads in order to deal with common 
+	  bridge misbehaviour regarding posted write flushing.
+	- Add some other conditionnal code for people who have to deal 
+	  with really broken bridges (they will have to edit a source 
+	  file to try these options).
+	- Handle correctly (hopefully) jiffies wrap-around.
+	- Restore the entry used to detect 875 until revision 0xff.
+	  (I removed it inadvertently, it seems :) )
+	- Replace __initfunc() which is deprecated stuff by __init which 
+	  is not yet so. ;-)
+	- Rewrite the MESSAGE IN scripts more generic by using a MOVE 
+	  table indirect. Extended messages of any size are accepted now.
+	  (Size is limited to 8 for now, but a constant is just to be 
+	  increased if necessary)
+	- Fix some bug in the fully untested MDP handling:) and share 
+	  some code between MDP handling and residual calculation.
+	- Calculate the data transfer residual as the 2's complement 
+	  integer (A positive value in returned on data overrun, and 
+	  a negative one on underrun).
+	- Add support of some 'resource handling' for linux-2.3.13.
+	  Basically the BARs have been changed to something more complex 
+	  in the pci_dev structure.
+	- Remove some deprecated code.
+
+Sat Jun  5  11:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5c
+	- Donnot negotiate on auto-sense if we are currently using 8 bit 
+	  async transfer for the target.
+	- Only check for SISL/RAID on i386 platforms.
+	  (A problem has been reported on PPC with that code).
+	- On MSG REJECT for a negotiation, the driver attempted to restart 
+	  the SCRIPT processor when this one was already running.
+
+Sat May 29  12:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5b
+	- Force negotiation prior auto-sense.
+	  This ensures that the driver will be able to grab the sense data 
+	  from a device that has received a BUS DEVICE RESET message from 
+	  another initiator.
+	- Complete all disconnected CCBs for a logical UNIT if we are told 
+	  about a UNIT ATTENTION for a RESET condition by this target.
+	- Add the control command 'cleardev' that allows to send a ABORT  
+	  message to a logical UNIT (for test purpose).
+
+Tue May 25  23:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5a
+	- Add support for task abort and bus device reset SCSI message 
+	  and implement proper synchonisation with SCRIPTS to handle 
+          correctly task abortion without races.
+	- Send an ABORT message (if untagged) or ABORT TAG message (if tagged)
+	  when the driver is told to abort a command that is disconnected and 
+	  complete the command with appropriate error.
+	  If the aborted command is not yet started, remove it from the start 
+	  queue and complete it with error.
+	- Add the control command 'resetdev' that allows to send a BUS 
+	  DEVICE RESET message to a target (for test purpose).
+	- Clean-up some unused or useless code.
+
+Fri May 21  23:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.5
+	- Add support for CHMOV with Wide controllers.
+	- Handling of the SWIDE (low byte residue at the end of a CHMOV 
+	  in DATA IN phase with WIDE transfer when the byte count gets odd).
+	- Handling of the IGNORE WIDE RESIDUE message.
+	  Handled from SCRIPTS as possible with some optimizations when both 
+	  a wide device and the controller are odd at the same time (SWIDE 
+	  present and IGNORE WIDE RESIDUE message on the BUS at the same time).
+	- Check against data OVERRUN/UNDERRUN condition at the end of a data 
+	  transfer, whatever a SWIDE is present (OVERRUN in DATA IN phase) 
+	  or the SODL is full (UNDERRUN in DATA out phase).
+	- Handling of the MODIFY DATA POINTER message.
+	  This one cannot be handled from SCRIPTS, but hopefully it will not
+	  happen very often. :)
+	- Large rewrite of the SCSI MESSAGE handling.
+
+Sun May 9  11:00 1999 Gerard Roudier (groudier@club-internet.fr)
+	* version sym53c8xx-1.4
+	- Support for IMMEDIATE ARBITRATION.
+	  See the README file for detailed information about this feature.
+	  Requires both a compile option and a boot option.
+	- Minor SCRIPTS optimization in reselection pattern for LUN 0.
+	- Simpler algorithm to deal with SCSI command starvation.
+	  Just use 2 tag counters in flip/flop and switch to the other 
+	  one every 3 seconds.
+	- Do some work in SCRIPTS after the SELECT instruction and prior 
+	  to testing for a PHASE. SYMBIOS say this feature is working fine. 
+	  (Btw, only problems with Toshiba 3401B had been reported).
+	- Measure the PCI clock speed and donnot attach controllers if 
+	  result is greater than 37 MHz. Since the precision of the 
+	  algorithm (from Stefan Esser) is better than 2%, this should 
+	  be fine.
 	- Fix the misdetection of SYM53C875E (was detected as a 876).
 	- Fix the misdetection of SYM53C810 not A (was detected as a 810A).
+	- Support for up to 256 TAGS per LUN (CMD_PER_LUN).
+	  Currently limited to 255 due to Linux limitation. :)
+	- Support for up to 508 active commands (CAN_QUEUE).
 	- Support for the 53C895A by Pamela Delaney <pam.delaney@lsil.com>
 	  The 53C895A contains all of the features of the 896 but has only 
 	  one channel and has a 32 bit PCI bus. It does 64 bit PCI addressing 
 	  using dual cycle PCI data transfers.
-	- Call request_region() event if MMIO is used and not normal IO.
-	  This allows sym and the ncr driver to be loaded in any order 
-	  without any risk of attaching the same device.
-	- Set the actual host ID used for each host in the scsi host data 
-	  structure. The mid-layer SCSI driver needs this information.
 	- Miscellaneous minor fixes.
+	- Some additions to the README.ncr53c8xx file.
