9272dcc232 pata_cs5536: Add support for non-X86_32 platforms
pata_cs5536 does work on the other platforms(e.g. Loongson, a MIPS
variant), so, remove the dependency of X86_32 and fix the building
errors under the other platforms via only reserving the X86_32 specific
parts for X86_32.

pata_amd also supports cs5536 IDE controller, but this one saves about
33k for the compressed kernel image(vmlinuz for MIPS).

9a7780c9ac libata-sff: make BMDMA optional
Make BMDMA optional depending on new config variable CONFIG_ATA_BMDMA.
In Kconfig, drivers are grouped into five groups - non-SFF native, SFF
w/ custom DMA interface, SFF w/ BMDMA, PIO-only SFF, and generic
fallback / legacy ones.  Kconfig and Makefile are reorganized
according to the groups and ordered alphabetically inside each group.

ata_ioports.bmdma_addr and ata_port.bmdma_prd[_dma] are put into
CONFIG_ATA_BMDMA, as are all bmdma related ops, variables and
functions.

This increase the binary size slightly when BMDMA is enabled but on
both native-only and PIO-only configurations the size is slightly
reduced.  Either way, the size difference is insignificant.  This
change is more meaningful to signify the separation between SFF and
BMDMA and as a tool to verify the separation.

2370b5ed03 ACPI: do not select ACPI_DOCK from ATA_ACPI
In March 2008 commit 0ac4a3c2fb ("ACPI: fix
ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because
of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m.

However, in September 2008 commit 898b054f3e
("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.

This makes the kernel ~5 Kb smaller for people who don't have a dock by
allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y.

This is a libata driver for the "macio" IDE controller used on most Apple
PowerMac and PowerBooks. It's a libata equivalent of drivers/ide/ppc/pmac.c

It supports all the features of its predecessor, including mediabay hotplug
and suspend/resume. It should also support module load/unload.

The timing calculations have been simplified to use pre-calculated tables
compared to drivers/ide/pmac.c and it uses the new mediabay interface
provided by a previous patch.

6521148c64 libata: add command name parsing for error output
This patch improve libata's output for error/notification messages
to allow easier comprehension and debugging:

When ATAPI commands issued through the SCSI layer fail, use SCSI
functions to print the CDB in human-readable form instead of just
dumping out the CDB in hex.

Print out the name of the failed command (as defined by the ATA
specification) in error handling output along with the raw register
contents.

When reporting status of ACPI taskfile commands executed on resume,
also output the names of the commands being executed (or not) in
readable form.

Since the extra data for printing command names increases kernel
size slightly, a config option has been added to allow disabling
command name output (as well as some of the error register parsing)
for those highly sensitive to kernel text size.

5b66c829bf ahci, pata_marvell: play nicely together
I've been chasing Jeff about this for months.  Jeff added the Marvell
device identifiers to the ahci driver without making the AHCI driver
handle the PATA port. This means a lot of users can't use current
kernels and in most distro cases can't even install.

This has been going on since March 2008 for the 6121 Marvell, and late 2007
for the 6145!!!

This was all pointed out at the time and repeatedly ignored. Bugs assigned
to Jeff about this are ignored also.

To quote Jeff in email

> "Just switch the order of 'ahci' and 'pata_marvell' in
> /etc/modprobe.conf, then use Fedora's tools regenerate the initrd.

> See?  It's not rocket science, and the current configuration can be
> easily made to work for Fedora users."

(Which isn't trivial, isn't end user, shouldn't be needed, and as it usually
breaks at install time is in fact impossible)

To quote Jeff in August 2007

> "   mv-ahci-pata
> Marvell 6121/6141 PATA support.  Needs fixing in the 'PATA controller
> command' area before it is usable, and can go upstream."

Only he add the ids anyway later and caused regressions, adding a further
id in March causing more regresions.

The actual fix for the moment is very simple. If the user has included
the pata_marvell driver let it drive the ports. If they've only selected
for SATA support give them the AHCI driver which will run the port a fraction
faster. Allow the user to control this decision via ahci.marvell_enable as
a module parameter so that distributions can ship 'it works' defaults and
smarter users (or config tools) can then flip it over it desired.

works around a bug in some BIOSes that handle unaligned access to the
PCI config registers poorly.  Finally, the driver allows fallback to
using MSR registers for configuration on BIOSes that are truly
broken.

7c9ef8e418 AVR32 PATA driver
Updated and simplified driver. Use only register transfer timing for both
data and register transfers. This gives poorer performance in PIO1 and 2,
but should not be a problem in PIO3 and 4, correct me if I'm wrong :)

The driver works very we'll but I still wonder about the interrupts. I have
an interrupt line, that works nicely when POLLING flag is not set. The
problem is the number of interrupts that eat away my CPU cycles.

When using the POLLING flag there seem to be some interrupts that dosen't get
cleared. Furthermore the device dosen't drive INTRQ high, it stays at 2.5 volts
and generates a lot of interrupts due to ripple / noise. What to do?

The HPT343/345 (aka 363) is a bit of a warped device.  For many setups you
need to access the other registers via BAR4 offsets.  PIO is now rock
solid, DMA isn't.  Unfortunately the drivers/ide hpt34x driver is

8cdfb29c0c libata/IDE: remove combined mode quirk
Both old-IDE and libata should be able handle all controllers and
devices found using normal resource reservation methods.

This eliminates the awful, low-performing split-driver configuration
where old-IDE drove the PATA portion of a PCI device, in PIO-only mode,
and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
Typically vendors would ship SATA hard drive / PATA optical
configuration, which would lend itself to slow (PIO-only) CD-ROM
performance.

For Intel users running in combined mode, it is now wholly dependent on
your driver choice (potentially link order, if you compile both drivers
in) whether old-IDE or libata will drive your hardware.

In either case, you will get full performance from both SATA and PATA
ports now, without having to pass a kernel command line parameter.

8cdf92a98f Fix Maple PATA IRQ assignment.
On the Maple board, the AMD8111 IDE is in legacy mode... except that it
appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by
the architecture's "pci_get_legacy_ide_irq()" function, but in libata we
just hard-code the numbers 14 and 15.

This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as
appropriate, having added a pci_dev argument to the
ATA_{PRIM,SECOND}ARY_IRQ macros.

There's probably a better way to do this -- especially if we observe
that the _only_ case in which this seemingly-generic
"pci_get_legacy_ide_irq()" function returns anything other than 14 and
15 for primary and secondary respectively is the case of the AMD8111 on
the Maple board -- couldn't we handle that with a special case in the
pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into
native mode during early boot and assign resources properly?
