Calxeda highbank SATA phy has intermittent problems bringing up a link
with Gen3 drives. Retrying the phy hard reset can work-around this issue,
but each reset also disables spread spectrum support. The reset function
also needs to reprogram the phy to enable spread spectrum support.
Create a new driver based on ahci_platform to support the Calxeda Highbank
SATA controller.

I followed the advice to not use the deprecated old PATA subsystem
ATA/ATAPI/MFM/RLL support (DEPRECATED) --->
and use the ATA subsystem instead.
Serial ATA and Parallel ATA drivers --->
Unfortunately I needed several tries to find out, that I needed the SFF
menu I had not selected before because I had never heard that term
before. I think it would have helped me, to have PATA or legacy IDE in
that item’s name.

Add basic support for pata on iMX. It has been tested only on imx51.
SDMA support will probably be added later so this version supports only
PIO.
v2:
- enable only when needed IORDY
- use dev_get_drvdata
v3:
- add missing clk_put() calls
- use platform_get_irq()
- fix resume code to avoid disabling IORDY on resume
v4:
- Remove EXPERIMENTAL and switch to depends on ARCH_MXC
- Use devm_kzalloc()
- make clock a must-have
- Use only 1 ioremap

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

CONFIG_HAVE_PATA_PLATFORM, by virtue of where its defined, has a
dependency on CONFG_ATA and CONFIG_ATA_SFF. This causes Kconfig
warnings when it is selected by various architectures, such as
warning: (ARCH_VEXPRESS && <choice> || ARCH_RPC && <choice> || MACH_VPAC270 && ARCH_PXA || MACH_REALVIEW_PB11MP && ARCH_REALVIEW || MACH_REALVIEW_PBA8 && ARCH_REALVIEW || MACH_REALVIEW_PBX && ARCH_REALVIEW || MACH_BAST_IDE && ARCH_S3C2410 || MACH_ANUBIS && ARCH_S3C2410) selects HAVE_PATA_PLATFORM which has unmet direct dependencies (ATA && ATA_SFF)
Since this option is only used to control visibility of the
CONFIG_PATA_PLATFORM option and isn't itself visible in the menu,
it is straightforward to simply remove these dependencies rather
than adjust all the architectures.

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

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.

In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("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 898b054f3eec5921320ae8614b5bdd7b07ea5b43
("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.

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.

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.
