This patch series addresses several issues with NCR5380 drivers:
1. The complex network of #include directives.
2. Three inconsistent implementations of the core driver all attempting
to share the same macro definitions in NCR5380.h.
3. Broken debugging code.
In the past these issues have led to compiler warnings and ugly hacks to
fix build failures.
This patch series fixes the debugging code by reducing the divergence
between the various core driver implementations.
The final two patches in the series further reduce divergence by refactoring
sun3_scsi.c and sun3_scsi_vme.c so that they follow the same structure as
the other NCR5380 drivers.
By the end of this patch series over 800 net lines of code have been
removed. This is mostly duplicated code that's easily eliminated once the
debugging code is made consistent (and some dead code is removed).
Better uniformity and less duplication should assist future work such as
modernization and trivial clean-up.
To make code review easier I've tried to keep these patches succinct and
free of extraneous changes. Though I did run checkpatch.pl, I've ignored
whitespace issues in existing code. I will send separate patches for
whitespace clean-up of NCR5380 drivers.
All NCR5380 drivers have been compile-tested with this patch series:
arm/cumana_1.c
arm/oak.c
atari_scsi.c
dmx3191d.c
dtc.c
g_NCR5380.c
g_NCR5380_mmio.c
mac_scsi.c
pas16.c
sun3_scsi.c
sun3_scsi_vme.c
t128.c
I've successfully regression tested this patch series using mac_scsi on a
PowerBook 180. The debugging macros are now usable again.

Subject: [PATCH 01/12] scsi/NCR5380: remove unused BOARD_NORMAL and BOARD_NCR53C400
References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-BOARD-macros
BOARD_NORMAL is completely unused and BOARD_NCR53C400 is used only by
g_NCR5380 internally. Remove the unused definitions.

References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-debug-macros-sun3-NCR5380_print
Only the NCR5380_dprint() macro should invoke the NCR5380_print() function.
That's why NCR5380.c only defines the function #if NDEBUG. Use the standard
macro.

References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-debug-macros-build-failures
The change from cmd->target to cmd->device->id was apparently the purpose of
commit a7f251228390e87d86c5e3846f99a455517fdd8e in
kernel/git/tglx/history.git but some instances have been missed.
Also fix the "NDEBUG_LAST_WRITE_SENT" and "NDEBUG_ALL" typo's.
Also fix some format strings (%ul becomes %lu) that caused compiler warnings.

Subject: [PATCH 06/12] scsi/NCR5380: fix dprintk macro usage and definition
References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-debug-macros-dprintk-params
There are three implementations of the core NCR5380 driver and three sets
of debugging macro definitions. And all three implementations use the
NCR5380.h header as well.
Two of the definitions of the dprintk macro accept a variable argument list
whereas the third does not. Standardize on the variable argument list.

Subject: [PATCH 07/12] scsi/NCR5380: adopt NCR5380_dprint() and NCR5380_dprint_phase()
References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-debug-macros-substitute-NCRPRINT
All NCR5380 drivers already include the NCR5380.h header. Better to
adopt those macros rather than have three variations on them.
Moreover, the macros in NCR5380.h are preferable anyway: the atari_NCR5380
and sun3_NCR5380 versions are inflexible. For example, they can't accomodate
NCR5380_dprint(NDEBUG_MAIN | NDEBUG_QUEUES, ...)
Replace the NCR_PRINT* macros from atari_NCR5380.h and sun3_NCR5380.h with
the equivalent macros from NCR5380.h.

Subject: [PATCH 09/12] scsi/NCR5380: fix and standardize NDEBUG macros
References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-debug-macros-fix-NDEBUG
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 f566a576bca09de85bf477fc0ab2c8c96405b77b 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
drivers/scsi/NCR5380.c:459: warning: 'NCR5380_print_phase' defined but not used
The debugging code is now enabled when NDEBUG != 0.

Subject: [PATCH 11/12] scsi/NCR5380: reduce depth of sun3_scsi nested includes
References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-sun3-includes
Move the #include "NCR5380.h" out of the sun3_scsi.h header file and into
the driver .c files, like all the other NCR5380 drivers in the tree.
This improves uniformity and reduces the depth of nested includes. The
sequence of #include's, #define's and #if's no longer does my head in.
Signed-off-by: Finn Thain <fthain@xxxxxxxxxxxxxxxxxxx>

Here's a graph showing the present #include structure.
sun3_scsi_vme.c -----> sun3_scsi.h -----> NCR5380.h
| ^
'--------------------|----.
| |
.----------------' |
| v
sun3_scsi.c -----> sun3_NCR5380.c
And here's the situation at the end of this patch series, after moving the
#includes with this patch, and merging sun3_scsi.c and sun3_scsi_vme with
the next patch.
sun3_scsi.h
^
|
|
sun3_scsi_vme.c -----> sun3_scsi.c -----> sun3_NCR5380.c
|
|
v
NCR5380.h
The final structure (see the next patch) of sun3_scsi_vme mirrors that of
g_NCR5380_mmio.c, and the final structure of sun3_scsi mirrors that of all
the other NCR5380 drivers.
BTW, both sun3_scsi.c and sun3_scsi_vme.c also #include "initio.h"
but I've sent a separate patch to address this.

Subject: [PATCH 12/12] scsi/NCR5380: merge sun3_scsi_vme.c into sun3_scsi.c
References: <20140318002822.372705594@xxxxxxxxxxxxxxxxxxx>
Content-Disposition: inline; filename=ncr5380-sun3-vme-merge
The sun3 drivers suffer from a whole bunch of duplicated code. Fix this
by following the g_NCR5380_mmio example. (Notionally, sun3_scsi relates to
sun3_scsi_vme in the same way that g_NCR5380 relates to g_NCR5380_mmio.)
Dead code is also removed: we now have working debug macros so
SUN3_SCSI_DEBUG is undesirable. Dead code within #ifdef OLD_DMA is also
dropped, consistent with sun3_scsi_vme.c.
