Collect together the components of several drivers and export eisa from
the i386-only area (It's not, it's on some alphas too). The code hasn't
been updated to work on the Alpha yet, but that can come later.
Repository copies were done a while ago.
Moving these now keeps them in consistant place across the 4.x series
as the newbusification progresses.

Update list of supported products.
Adjust probe message to include the ASC3030.
advansys.c:
Fix a long standing bug in the error recovery strategy. In order
to keep recovery simple, we freeze the SIMQ, stopping the XPT from
submitting new requests. Unfortunately, we also will freeze the
SIMQ if bus_dmamap_load blocks or we run out of controller resources.
On cards with limited resources it was possible to freeze the
SIM a second time and never unfreeze it. Now we more carefully
track our exception state so we never freeze the SIMQ more than
once.
Don't rely on pointers fitting in a 32bit field stored in the
per-transaction data structures on the card. Use an index to
an array of transaction mapping structures instead. This should
allow this driver to work on the Alpha.
Deal with the ASC3030 which is almost idistinguishable from the
ASC3050. Unfortunately the ASC3030 does not work at Ultra speeds,
so if we can't find an eeprom, we must assume that ultra is disabled.
The SIIG cards using the 3030 do not have eeproms. As a side effect,
we now honor the ultra disable bit in the eeprom if it is present.
Don't bother attempting to write corrected eeprom data back to the
eeprom. We can function just fine if the data is corrupted and
I'd rather not risk messing up the user's eeprom.
Modify the interrupt handler to catch latched external bus rests.
Dynamically determine the maximum number of S/G elements we can
map at a single time. The nature of the firmware interface for
these cards makes this value dependent on the number of "queues"
the card can support.

advmcode.h:
Synchronize with the latest firmware image released in the
Linux Advansys driver.
eisa_add_intr() which now takes an additional arguement (one of
EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE).
The flag RR_SHAREABLE has no effect when passed to
bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as
the eisa_alloc_resource() call (bus_alloc_resource method) now deals
with this flag directly, depending on the device ivars.
This change does nothing more than move all the 'shared = inb(foo + iobsse)'
nonesense to the device probe methods rather than the device attach.
Also, print out 'edge' or 'level' in the IRQ announcement message.

.. to 2.2.x and 3.x if people think it's worth it. Driver writers can do
this if it's not defined. (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)
NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.
camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".
- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.
- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.
- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases
cam_xpt.c, cam_sim.[ch], cam_ccb.h:
- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.
- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured
- bump the CAM version from 0x10 to 0x11
- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.
- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:
- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately
Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.

had a quirk that made a shim rather hard to implement properly and it was
just easier to convert the drivers in one go. The changes to the
buslogic driver go beyond just this - the whole driver was new-bus'ed
including pci and isa. I have only tested the EISA part of this so far.

for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.
These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine. This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in. It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.
PCI and EISA front ends will show up as soon as I get my hands on
the cards. There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)
