Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+Sat May 12 12:00 2001 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.7.3c
+        - Ensure LEDC bit in GPCNTL is cleared when reading the NVRAM.
+          Fix sent by Stig Telfer <stig@api-networks.com>.
+        - Backport from SYM-2 the work-around that allows to support 
+          hardwares that fail PCI parity checking.
+        - Check that we received at least 8 bytes of INQUIRY response 
+          for byte 7, that contains device capabilities, to be valid.
+        - Define scsi_set_pci_device() as nil for kernel < 2.4.4.
+        - + A couple of minor changes.
+          
+Sat Apr 7 19:30 2001 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.7.3b
+        - Fix an unaligned LOAD from scripts (was used as dummy read).
+        - In ncr_soft_reset(), only try to ABORT the current operation 
+          for chips that support SRUN bit in ISTAT1 and if SCRIPTS are 
+          currently running, as 896 and 1010 manuals suggest.
+        - In the CCB abort path, do not assume that the CCB is currently 
+          queued to SCRIPTS. This is not always true, notably after a 
+          QUEUE FULL status or when using untagged commands.
+
+Sun Mar 4 18:30 2001 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.7.3a
+        - Fix an issue in the ncr_int_udc() (unexpected disconnect)
+          handling. If the DSA didn't match a CCB, a bad write to 
+          memory could happen.
+
+Mon Feb 12 22:30 2001 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.7.3
+        - Support for hppa.
+          Tiny patch sent to me by Robert Hirst.
+        - Tiny patch for ia64 sent to me by Pamela Delaney.
+
+Tue Feb 6 13:30 2001 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.7.3-pre1
+        - Call pci_enable_device() as AC wants this to be done.
+        - Get both the BAR cookies used by CPU and actual PCI BAR 
+          values used from SCRIPTS. Recent PCI chips are able to 
+          access themselves using internal cycles, but they compare 
+          BAR values to destination address to make decision.
+          Earlier chips simply use PCI transactions to access IO 
+          registers from SCRIPTS.
+          The bus_dvma_to_mem() interface that reverses the actual 
+          PCI BAR value from the BAR cookie is now useless.
+          This point had been discussed at the list and the solution 
+          got approved by PCI code maintainer (Martin Mares).
+        - Merge changes for linux-2.4 that declare the host template 
+          in the driver object also when the driver is statically 
+          linked with the kernel.
+        - Increase SCSI message size up to 12 bytes, given that 8 
+          bytes was not enough for the PPR message (fix).
+        - Add field 'maxoffs_st' (max offset for ST data transfers).
+          The C1010 supports offset 62 in DT mode but only 31 in 
+          ST mode, to 2 different values for the max SCSI offset 
+          are needed. Replace the obviously wrong masking of the 
+          offset against 0x1f for ST mode by a lowering to 
+          maxoffs_st of the SCSI offset in ST mode.
+        - Refine a work-around for the C1010-66. Revision 1 does 
+          not requires extra cycles in DT DATA OUT phase.
+        - Add a missing endian-ization (abrt_tbl.addr).
+        - Minor clean-up in the np structure for fields accessed 
+          from SCRIPTS that requires special alignments.
+
+Sun Sep 24 21:30 2000 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.7.2
+        - Remove the hack for PPC added in previous driver version.
+        - Add FE_DAC feature bit to distinguish between 64 bit PCI 
+          addressing (FE_DAC) and 64 bit PCI interface (FE_64BIT).
+        - Get rid of the boot command line "ultra:" argument.
+          This parameter wasn't that clever since we can use "sync:" 
+          for Ultra/Ultra2 settings, and for Ultra3 we may want to 
+          pass PPR options (for now only DT clocking).
+        - Add FE_VARCLK feature bit that indicates that SCSI clock 
+          frequency may vary depending on board design and thus, 
+          the driver should try to evaluate the SCSI clock.
+        - Simplify the way the driver determine the SCSI clock:
+          ULTRA3 -> 160 MHz, ULTRA2 -> 80 MHz otherwise 40 MHz.
+          Measure the SCSI clock frequency if FE_VARCLK is set.
+        - Remove FE_CLK80 feature bit that got useless.
+        - Add support for the SYM53C875A (Pamela Delaney).
+
+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.
+
+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.
+        - Do not 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
+        - Do not 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 do not 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.
+        - Miscellaneous minor fixes.
+        - Some additions to the README.ncr53c8xx file.
+
+Tue Apr 15  10:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.3e
+        - Support for any number of LUNs (64) (SPI2-compliant).
+          (Btw, this may only be ever useful under linux-2.2 ;-))
+
+Sun Apr 11  10:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.3d
+        - Add 'hostid:#id' boot option. This option allows to change the 
+          default SCSI id the driver uses for controllers.
+        - Make SCRIPTS not use self-mastering for PCI.
+          There were still 2 places the driver used this feature of the 
+          53C8XX family.
+        - Move some data structures (nvram layouts and driver set-up) to 
+          the sym53c8xx_defs.h file. So, the both drivers will share them.
+        - Set MAX LUNS to 16 (instead of 8).
+
+Sat Mar 20  21:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.3b
+        - Add support for NCR PQS PDS.
+          James Bottomley <James.Bottomley@columbiasc.ncr.com>
+        - Allow value 0 for host ID.
+        - Support more than 8 controllers (> 40 in fact :-) )
+        - Add 'excl=#ioaddr' boot option: exclude controller.
+          (Version 1.3a driver)
+
+Thu Mar 11  23:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.3   (8xx-896 driver bundle)
+        - Equivalent changes as ncr53c8xx-3.2 due to the driver bundle.
+          (See Changelog.ncr53c8xx)
+        - Do a normal soft reset as first chip reset, since aborting current 
+          operation may raise an interrupt we are not able to handle since 
+          the interrupt handler is not yet established.
+
+Sat Mar 6  11:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.2b
+        - 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 21  20:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.2a
+        - The rewrite of the interrupt handling broke the SBMC interrupt 
+          handling due to a 1 bit mask tiny error. Hopefully fixed.
+        - If INQUIRY came from a scatter list, the driver looked into 
+          the scatterlist instead of the data.:) Since this should never
+          happen, we just discard the data if use_sg is not zero.
+
+Fri Feb 12  23:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.2
+        - Major rewrite of the interrupt handling and recovery stuff for 
+          the support of non compliant SCSI removal, insertion and all 
+          kinds of screw-up that may happen on the SCSI BUS.
+          Hopefully, the driver is now unbreakable or may-be, it is just 
+          quite brocken. :-)
+          Many thanks to Johnson Russel (Symbios) for having responded to 
+          my questions and for his interesting advices and comments about 
+          support of SCSI hot-plug.
+        - Add 'recovery' option to driver set-up.
+        - Negotiate SYNC data transfers with CCS devices.
+        - Deal correctly with 64 bit PCI address registers on Linux 2.2.
+          Pointed out by Leonard Zubkoff.
+
+Sun Jan 31  18:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.1a
+        - Some 896 chip revisions (all for now :-)), may hang-up if the 
+          soft reset bit is set at the wrong time while SCRIPTS are running.
+          We need to first abort the current SCRIPTS operation prior to 
+          resetting the chip. This fix has been sent to me by SYMBIOS/LSI 
+          and I just translated it into ncr53c8xx syntax.
+          Must be considered 100 % trustable, unless I did some mistake 
+          when translating it. :-)
+
+Sun Jan 24  18:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.1
+        - Major rewrite of the SCSI parity error handling.
+          The informations contained in the data manuals are incomplete about 
+          this feature.
+          I asked SYMBIOS about and got in reply the explanations that are 
+          _indeed_ missing in the data manuals.
+        - 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.
+        - Fix for 64 bit PCI address register calculation. (Lance Robinson)
+        - Fix for big-endian in phase mismatch handling. (Michal Jaegermann)
+
+Fri Jan  1  20:00 1999 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.0a
+        - Waiting list look-up didn't work for the first command of the list.
+          Hopefully fixed, but tested on paper only. ;)
+        - Remove the most part of PPC specific code for Linux-2.2.
+          Thanks to Cort.
+        - Some other minors changes.
+
+Sat Dec 19  21:00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version sym53c8xx-1.0
+        - Define some new IO registers for the 896 (istat1, mbox0, mbox1)
+        - Revamp slighly the Symbios NVRAM lay-out based on the excerpt of 
+          the header file I received from Symbios.
+        - Check the PCI bus number for the boot order (Using a fast 
+          PCI controller behing a PCI-PCI bridge seems sub-optimal).
+        - Disable overlapped PCI arbitration for the 896 revision 1.
+        - Reduce a bit the number of IO register reads for phase mismatch 
+          by reading DWORDS at a time instead of BYTES.
+
+Thu Dec  3  24:00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.18
+        - I received this afternoon a 896 from SYMBIOS and started testing  
+          the driver with this beast. After having fixed 3 buglets, it worked  
+          with all features enabled including the phase mismatch handling 
+          from SCRIPTS. Since this feature is not yet tested enough, the 
+          boot option 'ncr53c8xx=specf:1' is still required to enable the 
+          driver to handle PM from SCRIPTS. 
+
+Sun Nov 29  18:00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.17
+        - The SISL RAID change requires now remap_pci_mem() stuff to be 
+          compiled for __i386__ when normal IOs are used.
+        - The PCI memory read from SCRIPTS that should ensure ordering 
+          was in fact misplaced. BTW, this may explain why broken PCI 
+          device drivers regarding ordering are working so well. ;-)
+        - Rewrite ncr53c8xx_setup (boot command line options) since the  
+          binary code was a bit too bloated in my opinion.
+        - Make the code simpler in the wakeup_done routine.
+
+Tue Nov 24  23:00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.16
+        - Add SCSI_NCR_OPTIMIZE_896_1 compile option and 'optim' boot option.
+          When set, the driver unconditionnaly assumes that the interrupt 
+          handler is called for command completion, then clears INTF, scans 
+          the done queue and returns if some completed CCB is found. If no 
+          completed CCB are found, interrupt handling will proceed normally.
+          With a 896 that handles MA from SCRIPTS, this can be a great win, 
+          since the driver will never performs PCI read transactions, but 
+          only PCI write transactions that may be posted.
+          If the driver haven't to also raise the SIGP this would be perfect.
+          Even with this penalty, I think that this will work great.
+          Obviously this optimization makes sense only if the IRQ is not 
+          shared with another device.
+        - 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.
+
+Thu Nov 19  23:00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.15
+        - Add support for hardware LED control of the 896.
+        - Ignore chips that are driven by SISL RAID (DAC 960).
+          Change sent by Leonard Zubkoff and slightly reworked.
+        - Prevent 810A rev 11 and 860 rev 1 from using cache line based 
+          transactions since those early chip revisions may use such on 
+          LOAD/STORE instructions (work-around).
+        - Remove some useless and bloat code from the pci init stuff.
+        - Do not use the readX()/writeX() kernel functions for __i386__, 
+          since they perform useless masking operations in order to deal 
+          with broken driver in 2.1.X kernel.
+
+Wed Nov 11  10:00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.14
+        - The driver was unhappy when configured with default_tags > MAX_TAGS
+          Hopefully doubly-fixed.
+        - Set PCI_PARITY in PCI_COMMAND register in not set (PCI fix-up).
+        - Print out some message if phase mismatch is handled from SCRIPTS.
+
+Sun Nov 1  14H00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.13
+        - Some rewrite of the device detection code. This code had been 
+          patched too much and needed to be face-lifted a bit.
+          Remove all platform dependent fix-ups that was not needed or
+          conflicted with some other driver code as work-arounds.
+          Reread the NVRAM before the calling of ncr_attach(). This spares 
+          stack space and so allows to handle more boards.
+          Handle 64 bit base addresses under linux-2.0.X.
+          Set MASTER bit in PCI COMMAND register if not set.
+
+Wed Oct 30 22H00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.12
+        - Damned! I just broke the driver for Alpha by leaving a stale 
+          instruction in the source code. Hopefully fixed.
+        - Do not set PFEN when it is useless. Doing so we are sure that BOF 
+          will be active, since the manual appears to be very unclear on what 
+          feature is actually used by the chip when both PFEN and BOF are 
+          set.
+
+Sat Oct 24 16H00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.11
+        - LOAD/STORE instructions were miscompiled for register offsets 
+          beyond 0x7f. This broke accesses to 896' new registers.
+        - Disable by default Phase Mismatch handling from SCRIPTS, since 
+          current 896 rev.1 seems not to operate safely with the driver
+          when this feature is enabled (and above LOAD/STORE fix applied).
+          I will change the default to 'enabled' when this problem will be 
+          solved.
+          Using boot option 'ncr53c8xx=specf:1' enables this feature.
+        - Implement a work-around (DEL 472 - ITEM 5) that should allow the 
+          driver to safely enable hardware phase mismatch with 896 rev. 1.
+
+Tue Oct 20 22H00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.10
+        - Add the 53c876 description to the chip table. This is only useful 
+          for printing the right name of the controller.
+        - Add additional 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.
+        - 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.
+        - Use NAME53C and NAME53C8XX for chip name prefix chip family name.
+          Just give a try using "sym53c" and "sym53c8xx" instead of "ncr53c" 
+          and "ncr53c8xx". :-)
+
+Sun Oct 11 17H00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.9
+        - DEL-441 Item 2 work-around for the 53c876 rev <= 5 (0x15).
+        - Break ncr_scatter() into 2 functions in order to guarantee best 
+          possible code optimization for the case we get a scatter list.
+        - Add the code intended to support up to 1 tera-byte for 64 bit systems.
+          It is probably too early, but I wanted to complete the thing.
+
+Sat Oct 3 14H00 1998 Gerard Roudier (groudier@club-internet.fr)
+        * version pre-sym53c8xx-0.8
+        - Do some testing with io_mapped and fix what needed to be so.
+        - Wait for SCSI selection to complete or time-out immediately after 
+          the chip won arbitration, since executing SCRIPTS while the SCSI 
+          core is performing SCSI selection breaks the selection procedure 
+          at least for some chip revisions.
+        - Interrupt the SCRIPTS if a device does not go to MSG OUT phase after 
+          having been selected with ATN. Such a situation is not recoverable, 
+          better to fail when we are stuck.
