Thu May 11   12:30 2000 Pam Delaney ([e-mail])
	* revision 3.3b
 
Mon Apr 24 12:00 2000 Gerard Roudier ([e-mail])
	* revision 3.2i
	- Return value 1 (instead of 0) from the driver setup routine.
	- Let the driver also attach controllers that have been set to 
	  OFF in the NVRAM as it did prior to revision 3.2g.

Sat Apr 1  12:00 2000 Gerard Roudier ([e-mail])
	* revision 3.2h
	- Fix a compilation problem on Alpha introduced in version 3.2g.
          (`port' changed to `base_io').
	- Move from `sym' to this driver a tiny change for __sparc__ 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).

Thu Mar 16   9:30 2000 Pam Delaney ([e-mail])
	* revision 3.3b-3
 	- Added exclusion for the 53C1010 and 53C1010_66 chips
	  to the driver (change to sym53c8xx_comm.h).

Mon March 6  23:15 2000 Gerard Roudier ([e-mail])
	* revision 3.2g
	- Add the file sym53c8xx_comm.h that collects code that should 
	  be shared by sym53c8xx and ncr53c8xx drivers. For now, it is  
	  a header file that is only included by the ncr53c8xx driver, 
	  but things will be cleaned up later. This code addresses 
	  notably:
	  * Chip detection and PCI related initialisations
	  * NVRAM detection and reading
	  * DMA mapping
	  * Boot setup command
	  * And some other ...
	- Add support for the new dynamic dma mapping kernel interface.
	  Requires Linux-2.3.47 (tested with pre-2.3.47-6).
	- Get data transfer direction from the scsi command structure 
	  (Scsi_Cmnd) when this information is available.

Fri Jan 14 14:00 2000 Pam Delaney ([e-mail])
	* revision pre-3.3b-1
	- Merge parallel driver series 3.31 and 3.2e 

Tue Jan 11 14:00 2000 Pam Delaney ([e-mail])
	* revision 3.31
	- Added support for mounting disks on wide-narrow-wide
	  scsi configurations.  
	- Built off of version 3.30

Mon Jan 10 13:30 2000 Pam Delaney ([e-mail])
	* revision 3.30
	- Added capability to use the integrity checking code
	  in the kernel (optional).
	- Disabled support for the 53C1010.
	- Built off of version 3.2c

Sat Jan 8  22:00 2000 Gerard Roudier ([e-mail])
	* revision 3.2e
	- Add year 2000 copyright.
	- Display correctly bus signals when bus is detected wrong.
	- Remove the dead code that broke driver 3.2d.

Mon Dec 6  22:00 1999 Gerard Roudier ([e-mail])
	* revision 3.2d
	- 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 device/function).
	- Get rid of the old PCI bios interface, but preserve kernel 2.0 
	  compatibility from a simple wrapper.
	- Remove the compilation condition about having to acquire the 
	  io_request_lock since it seems to be a definite feature now.:)
	- proc_dir structure no longer needed for kernel >= 2.3.27.
	- Change the driver detection code by the sym53c8xx one, modulo 
	  some minor changes. The driver can now attach any number of 
	  controllers (>40) and does no longer hoger stack space at 
	  initialisation.
	- 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.
	- Update the poor Tekram sync factor table.
	- Remove the compilation condition about having to acquire the 
	  io_request_lock since it seems to be a definite feature now.:)
	- proc_dir structure no longer needed for kernel >= 2.3.27.

Sat Sep 11  18:00 1999 Gerard Roudier ([e-mail])
	* revision 3.2c
	- 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. ;-)
	- 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 May 10  11:00 1999 Gerard Roudier ([e-mail])
	* revision pre-3.2b-1
	- Support for the 53C895A by Pamela Delaney <[e-mail]>
	  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.
	- Miscellaneous minor fixes.
	- Some additions to the README.ncr53c8xx file.

Sun Apr 11  10:00 1999 Gerard Roudier ([e-mail])
	* revision 3.2a
	- Add 'hostid:#id' boot option. This option allows to change the 
	  default SCSI id the driver uses for controllers.
	- Remove nvram layouts and driver set-up structures from the C source,
	  and use the one defined in sym53c8xx_defs.h file.
	  (shared by both drivers).
	- Set for now MAX LUNS to 16 (instead of 8).

Thu Mar 11  23:00 1999 Gerard Roudier ([e-mail])
	* revision 3.2	  (8xx-896 driver bundle)
	- Only define the host template in ncr53c8xx.h and include the 
	  sym53c8xx_defs.h file.
	- Declare static all symbols that do not need to be visible from 
	  outside the driver code.
	- Add 'excl' boot command option that allows to pass to the driver 
	  io address of devices not to attach.
	- Add info() function called from the host template to print 
	  driver/host information.
	- Minor documentation additions.

Sat Mar 6  11:00 1999 Gerard Roudier ([e-mail])
	* revision 3.1h
	- Fix some oooold bug that hangs the bus if a device rejects a 
	  negotiation. Btw, the corresponding stuff also needed some cleanup 
	  and thus the change is a bit larger than it could have been.
	- Still some typo that made compilation fail for 64 bit (trivial fix).

Sun Feb  14:00 1999 Gerard Roudier ([e-mail])
	* revision 3.1g
	- Deal correctly with 64 bit PCI address registers on Linux 2.2.
	  Pointed out by Leonard Zubkoff.
	- Allow to tune request_irq() flags from the boot command line using 
	  ncr53c8xx=irqm:??, as follows:
	  a) If bit 0x10 is set in irqm, SA_SHIRQ flag is not used.
	  b) If bit 0x20 is set in irqm, SA_INTERRUPT flag is not used.
	  By default the driver uses both SA_SHIRQ and SA_INTERRUPT.
	  Option 'ncr53c8xx=irqm:0x20' may be used when an IRQ is shared by 
	  a 53C8XX adapter and a network board.
	- Tiny mispelling fixed (ABORT instead of ABRT). Was fortunately 
	  harmless.
	- Negotiate SYNC data transfers with CCS devices.

Sat Jan 16  17:30 1999 Gerard Roudier ([e-mail])
	* revision 3.1f
	- Some PCI fix-ups not needed any more for PPC (from Cort).
	- Cache line size set to 16 DWORDS for Sparc   (from DSM).
	- Waiting list look-up didn't work for the first command of the list.
	- Remove 2 useless lines of code.

Sun Dec 13  18:00 1998 Gerard Roudier ([e-mail])
	* revision 3.1e
	- Same work-around as for the 53c876 rev <= 0x15 for 53c896 rev 1:
	  Disable overlapped arbitration. This will not make difference 
	  since the chip has on-chip RAM.

Thu Nov 26  22:00 1998 Gerard Roudier ([e-mail])
	* revision 3.1d
	- The SISL RAID change requires now remap_pci_mem() stuff to be 
	  compiled for __i386__ when normal IOs are used.
	- Minor spelling fixes in doc files.

Sat Nov 21  18:00 1998 Gerard Roudier ([e-mail])
	* revision 3.1c
	- Ignore chips that are driven by SISL RAID (DAC 960).
	  Change sent by Leonard Zubkoff and slightly reworked.
	- Still a buglet in the tags initial settings that needed to be fixed.
	  It was not possible to disable TGQ at system startup for devices 
	  that claim TGQ support. The driver used at least 2 for the queue 
	  depth but did'nt keep track of user settings for tags depth lower 
	  than 2.

Wed Nov 11  10:00 1998 Gerard Roudier ([e-mail])
	* revision 3.1b
	- The driver was unhappy when configured with default_tags > MAX_TAGS
	  Hopefully doubly-fixed.
	- Update the Configure.help driver section that speaks of TAGS.

Wed Oct 21 21:00 1998 Gerard Roudier ([e-mail])
	* revision 3.1a
	- Changes from Eddie Dost for Sparc and Alpha:
	  ioremap/iounmap support for Sparc.
	  pcivtophys changed to bus_dvma_to_phys.
	- Add the 53c876 description to the chip table. This is only usefull 
	  for printing the right name of the controller.
	- DEL-441 Item 2 work-around for the 53c876 rev <= 5 (0x15).
	- Add additionnal checking of INQUIRY data:
	  Check INQUIRY data received length is at least 7. Byte 7 of 
	  inquiry data contains device features bits and the driver might 
	  be confused by garbage. Also check peripheral qualifier.
	- Cleanup of the SCSI tasks management:
	  Remove the special case for 32 tags. Now the driver only uses the 
	  scheme that allows up to 64 tags per LUN.
	  Merge some code from the 896 driver.
	  Use a 1,3,5,...MAXTAGS*2+1 tag numbering. Previous driver could  
	  use any tag number from 1 to 253 and some non conformant devices  
	  might have problems with large tag numbers.
	- 'no_sync' changed to 'no_disc' in the README file. This is an old 
	  and trivial mistake that seems to demonstrate the README file is 
	  not often read. :)

Sun Oct  4 14:00 1998 Gerard Roudier ([e-mail])
	* revision 3.0i
	- Cosmetic changes for sparc (but not for the driver) that needs
