b87dbd50a9 PR: kern/20895
PR kern/20895:
- Add FE_DAC new feature flag to distinguish between
  64 bit PCI addressing (DAC cycles) and 64 bit PCI
  interface (64 bit Memory BARs).
- Properly deal with chips that have a 32 bit PCI
  interface but support and may generate DAC.
  (Only SYM53C895A for now).

PR misc/17584 (at least partially addressed):
- Try detecting hardware combinations that trigger
  spurious PCI master parity error detections by the
  PCI chip. This work-around is implemented in the
  `snooptest' routine and consists in retrying with
  PCI master parity checking disabled if such an
  error is reported by the PCI chip during this test.

Other:
- Fix a tiny bug in WIDE negotiation that was very
  unlikely to be triggerred. The BUS width was wrongly
  compared against chip's max. offset.

3bf3b0d199 - Make the NVRAM debug code compile and work.
- Get rid of a fiew uselessly `long' variables
  and casts to `long'.
- Estimate the PCI clock for all chips, except
  C1010 for now (we should do that for each PCI BUS)
- Refine a couple of C1010 errata work-arounds.
- For now, make sure AIP generation is disabled
  for the C1010-66.

22b8c23cfa This new version adds support for early NCR chips.
53C810 non 'A', 53C815 and 53C825 non 'A' are now
attached by the driver (by default).
The driver uses a different SCRIPTS set based on
MEMORY MOVE instructions for these chips.

2 SCRIPTS sets (firmwares) numbered #1 and #2 are
used for the whole support of the 53C8XX family
to get possible:

- FW #1 : Only based on MEMORY MOVE instructions.
          Selected for 810, 815, 825.
- FW #2 : LOAD/STORE based. This is the firmware
          also used by previous driver versions.
          Selected for other chips.

When both `ncr' and `sym' are configured, `sym'
will now attach all the 53C8XX devices by default.
Previous balancing between `ncr' and `sym' can be
preserved by:

- Either editing sym_conf.h and commenting the
  following compile option:
     #define SYM_CONF_GENERIC_SUPPORT
  (This also saves about 3.5Kb of kernel memory).

- Or setting kernel config option
    SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40)

1b13703051 - Add year 2000 copyright to driver files.
- Set MAX_OFFS driver compile option to 63 (was 64 which is wrong).
  - Fix a typo in the SYMBIOS NVRAM layout structure and add field and
    bit definition for the support of PIM_NOBUSRESET.
  - Report to XPT PIM_NOBUSRESET and PIM_SCANHILO if set by user in NVRAM.
  - Negotiate SYNC immediately after WIDE response from the target as
    suggested by Justin Gibbs.
  - Remove some misleading comment about CmdQue handling by CAM.
  - Apply correctly the MAX_WIDE and MAX_OFFS driver options.

1b3fcf60f7 - Add device entry for the next generation of C1010 device
(pci dev_id 0x21).
- Start the SCRIPTS processor without resetting the SCSI BUS
  at initialization.
- Remove the "Host adapter CCB chain" (got useless given the
  new queuing scheme).
- Display correctly the state of SCSI signals, when SCSI BUS
  looks bad.
- Cosmetic changes in messages printed out at initialization.
- Notifications and messages on RESET conditions slightly
  reworked.
- TEKRAM 24C16 NVRAM support fixed (also reported ok).

cf4d6e3c72 Go ahead and take these off the vendor branch as Gerard Roudier is now
a committer and will be maintaining these in the usual manner.

Add $FreeBSD$'s to get them off on the right foot.

4daec0d51e * The C1010 stepping B0 (Rev 1) tested OK for DT transfers without the U3EN
broken bit work-around enabled.
* Fixed a bug that made MDP not work. (However, MDP is actually not tested
  due to lack of hardware using this feature).
* Chip table changed to support the C1010 B0 w/o the U3EN bit work-around
  enabled.
* Add the SYM_SETUP_MAX_LUN, SYM_SETUP_LP_PROBE_MAP (used to tell the
  driver about chips that are to be claimed with lower priority than old
  PCI bus based driver (typically the ncr)), SYM_SETUP_SCSI_DIFF, and
  SYM_SETUP_PCI_PARITY options.

803caabbae New `sym' device driver optimized for the Symbios/LSI 53C896/53C895A/53C1010
PCI SCSI controllers.  This driver also supports the following Symbios/LSI
PCI SCSI chips: 53C810A, 53C825A, 53C860, 53C875, 53C876, 53C885, 53C895.

However, it does NOT support earlier chips as the following ones: 53C810,
53C815, 53C825.

See README.sym for more details.
