After 3.22 firmware, PMC firmware guys tell us the

be 10 secs to avoid a PCIe error due to the driver
looking at the controller too soon after the reset.

The acornscsi driver was added in v2.1.88. It has always #undef-ed
CONFIG_SCSI_ACORNSCSI_LINK near the top of acornscsi.c. And, just to be
sure, it has also always triggered a preprocessor error if
CONFIG_SCSI_ACORNSCSI_LINK was still defined. But, as far as I can see,
it has never even been possible to set SCSI_ACORNSCSI_LINK through
kconfig, or its predecessors, in the first place.

Error handling in UFS driver is broken and resets the host controller
for fatal errors without re-initialization. Correct the fatal error
handling sequence according to UFS Host Controller Interface (HCI)
v1.1 specification.
o Processed requests which are completed w/wo error are reported to
SCSI layer and any pending commands that are not started are aborted
in the controller and re-queued into scsi mid-layer queue.
o Upon determining fatal error condition the host controller may hang
forever until a reset is applied. Block SCSI layer for sending new
requests and apply reset in a separate error handling work.
o SCSI is informed about the expected Unit-Attention exception from the
device for the immediate command after a reset so that the SCSI layer
take necessary steps to establish communication with the device.

As of now SCSI initiated error handling is broken because,
the reset APIs don't try to bring back the device initialized and
ready for further transfers.
In case of timeouts, the scsi error handler takes care of handling aborts
and resets. Improve the error handling in such scenario by resetting the
device and host and re-initializing them in proper manner.

There is a possible race condition in the hardware when the abort
command is issued to terminate the ongoing SCSI command as described
below:
- A bit in the door-bell register is set in the controller for a
new SCSI command.
- In some rare situations, before controller get a chance to issue
the command to the device, the software issued an abort command.
- If the device recieves abort command first then it returns success
because the command itself is not present.
- Now if the controller commits the command to device it will be
processed.
- Software thinks that command is aborted and proceed while still
the device is processing it.
- The software, controller and device may go out of sync because of
this race condition.
To avoid this, query task presence in the device before sending abort
task command so that after the abort operation, the command is guaranteed
to be non-existent in both controller and the device.

Currently, sending Task Management (TM) command to the card might
be broken in some scenarios as listed below:
Problem: If there are more than 8 TM commands the implementation
returns error to the caller.
Fix: Wait for one of the slots to be emptied and send the command.
Problem: Sometimes it is necessary for the caller to know the TM service
response code to determine the task status.
Fix: Propogate the service response to the caller.
Problem: If the TM command times out no proper error recovery is
implemented.
Fix: Clear the command in the controller door-bell register, so that
further commands for the same slot don't fail.
Problem: While preparing the TM command descriptor, the task tag used
should be unique across SCSI/NOP/QUERY/TM commands and not the
task tag of the command which the TM command is trying to manage.
Fix: Use a unique task tag instead of task tag of SCSI command.
Problem: Since the TM command involves H/W communication, abruptly ending
the request on kill interrupt signal might cause h/w malfunction.
Fix: Wait for hardware completion interrupt with TASK_UNINTERRUPTIBLE
set.

All three NCR5380 core driver implementations share the same NCR5380.h
header file so they need to agree on certain macro definitions.
The flag bit used by the NDEBUG_MERGING macro in atari_NCR5380 and
sun3_NCR5380 collides with the bit used by NDEBUG_LISTS.
Moreover, NDEBUG_ABORT appears in NCR5380.c so it should be defined in
NCR5380.h rather than in each of the many drivers using that core.
An undefined NDEBUG_ABORT macro caused compiler errors and led to dodgy
workarounds in the core driver that can now be removed.
(See commits f566a576bc and
185a7a1cd79b9891e3c17abdb103ba1c98d6ca7a.)
Move all of the NDEBUG_ABORT, NDEBUG_TAGS and NDEBUG_MERGING macro
definitions into NCR5380.h where all the other NDEBUG macros live.
Also, incorrect "#ifdef NDEBUG" becomes "#if NDEBUG" to fix the warning:
drivers/scsi/mac_scsi.c: At top level:
drivers/scsi/NCR5380.c:418: warning: 'NCR5380_print' defined but not used
