ACS-3 introduced the ATA Identify Device Data log as mandatory. A
warning message currently signals to the user if a device does not
report supporting this log page in the log directory page, regardless
of the ATA version of the device. Furthermore, this warning will appear
for all attempts at accessing this missing log page during device
revalidation.
Since it is useless to constantly access the log directory and warn
about this lack of support once we have discovered that the device
does not support this log page, introduce the horkage flag
ATA_HORKAGE_NO_ID_DEV_LOG to mark a device as lacking support for
the Identify Device Data log page. Set this flag when
ata_log_supported() returns false in ata_identify_page_supported().
The warning is printed only if the device ATA level is 10 or above
(ACS-3 or above), and only once on device scan. With this flag set, the
log directory page is not accessed again to test for Identify Device
Data log page support.

Some ATA drives are very slow to respond to READ_LOG_EXT and
READ_LOG_DMA_EXT commands issued from ata_dev_configure() when the
device is revalidated right after resuming a system or inserting the
ATA adapter driver (e.g. ahci). The default 5s timeout
(ATA_EH_CMD_DFL_TIMEOUT) used for these commands is too short, causing
errors during the device configuration. Ex:
...
ata9: SATA max UDMA/133 abar m524288@0x9d200000 port 0x9d200400 irq 209
ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata9.00: ATA-9: XXX XXXXXXXXXXXXXXX, XXXXXXXX, max UDMA/133
ata9.00: qc timeout (cmd 0x2f)
ata9.00: Read log page 0x00 failed, Emask 0x4
ata9.00: Read log page 0x00 failed, Emask 0x40
ata9.00: NCQ Send/Recv Log not supported
ata9.00: Read log page 0x08 failed, Emask 0x40
ata9.00: 27344764928 sectors, multi 16: LBA48 NCQ (depth 32), AA
ata9.00: Read log page 0x00 failed, Emask 0x40
ata9.00: ATA Identify Device Log not supported
ata9.00: failed to set xfermode (err_mask=0x40)
ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata9.00: configured for UDMA/133
...
The timeout error causes a soft reset of the drive link, followed in
most cases by a successful revalidation as that give enough time to the
drive to become fully ready to quickly process the read log commands.
However, in some cases, this also fails resulting in the device being
dropped.
Fix this by using adding the ata_eh_revalidate_timeouts entries for the
READ_LOG_EXT and READ_LOG_DMA_EXT commands. This defines a timeout
increased to 15s, retriable one time.

Many users are reporting that the Samsung 860 and 870 SSD are having
various issues when combined with AMD/ATI (vendor ID 0x1002) SATA
controllers and only completely disabling NCQ helps to avoid these
issues.
Always disabling NCQ for Samsung 860/870 SSDs regardless of the host
SATA adapter vendor will cause I/O performance degradation with well
behaved adapters. To limit the performance impact to ATI adapters,
introduce the ATA_HORKAGE_NO_NCQ_ON_ATI flag to force disable NCQ
only for these adapters.
Also, two libata.force parameters (noncqati and ncqati) are introduced
to disable and enable the NCQ for the system which equipped with ATI
SATA adapter and Samsung 860 and 870 SSDs. The user can determine NCQ
function to be enabled or disabled according to the demand.
After verifying the chipset from the user reports, the issue appears
on AMD/ATI SB7x0/SB8x0/SB9x0 SATA Controllers and does not appear on
recent AMD SATA adapters. The vendor ID of ATI should be 0x1002.
Therefore, ATA_HORKAGE_NO_NCQ_ON_AMD was modified to
ATA_HORKAGE_NO_NCQ_ON_ATI.

But there is a large number of users which is still reporting issues

Marvell SATA controllers and all reporters also report these problems

Note that with AMD SATA controllers users are reporting even worse

Currently, the only way a user can determine if a SATA device supports
NCQ priority is to try to enable the use of this feature using the
ncq_prio_enable sysfs device attribute. If enabling the feature fails,
it is because the device does not support NCQ priority. Otherwise, the
feature is enabled and success indicates that the device supports NCQ
priority.
Improve this odd interface by introducing the read-only
ncq_prio_supported sysfs device attribute to indicate if a SATA device
supports NCQ priority. The value of this attribute reflects the status
of device flag ATA_DFLAG_NCQ_PRIO, which is set only for devices
supporting NCQ priority.
Add this new sysfs attribute to the device attributes group of libahci
and libata-sata.

Print a list of features supported by a drive when it is configured in
ata_dev_configure() using the new function ata_dev_print_features().
The features printed are not already advertized and are: trusted
send-recev support, device attention support, device sleep support,
NCQ send-recv support and NCQ priority support.

Support for the READ LOG PAGE DMA EXT command is indicated by words 119
and 120 of a device identify data. This is tested in
ata_read_log_page() with ata_id_has_read_log_dma_ext() and the
READ LOG PAGE DMA command used if the device reports supports for it.
However, some devices lie about this support and using the DMA version
of the command fails, generating the warning message "READ LOG DMA EXT
failed, trying PIO". Since READ LOG PAGE DMA EXT is an optional command,
this warning is not at all important but may be scary for the user.
Change ata_read_log_page() to suppres this warning and to print an
error message if both DMA and PIO attempts failed.
With this change, there is no need to print again an error message when
ata_read_log_page() returns an error. So simplify the users of this
function.

The ata device flag ATA_DFLAG_NCQ_PRIO indicates if a device supports
the NCQ Priority feature while the ATA_DFLAG_NCQ_PRIO_ENABLE device
flag indicates if the feature is enabled. Enabling NCQ priority use is
controlled by the user through the device sysfs attribute
ncq_prio_enable. As a result, the ATA_DFLAG_NCQ_PRIO flag should not be
cleared when ATA_DFLAG_NCQ_PRIO_ENABLE is not set as the device still
supports the feature even after the user disables it. This leads to the
following cleanups:
- In ata_build_rw_tf(), set a command high priority bit based on the
ATA_DFLAG_NCQ_PRIO_ENABLE flag, not on the ATA_DFLAG_NCQ flag. That
is, set a command high priority only if the user enabled NCQ priority
use.
- In ata_dev_config_ncq_prio(), ATA_DFLAG_NCQ_PRIO should not be cleared
if ATA_DFLAG_NCQ_PRIO_ENABLE is not set. If the device does not
support NCQ priority, both ATA_DFLAG_NCQ_PRIO and
ATA_DFLAG_NCQ_PRIO_ENABLE must be cleared.
With the above ata_dev_config_ncq_prio() change, ATA_DFLAG_NCQ_PRIO flag
is set on device scan and revalidation. There is no need to trigger a
device revalidation in ata_ncq_prio_enable_store() when the user enables
the use of NCQ priority. Remove the revalidation code from that funciton
to simplify it. Also change the return value from -EIO to -EINVAL when a
user tries to enable NCQ priority for a device that does not support
this feature. While at it, also simplify ata_ncq_prio_enable_show().
Overall, there is no functional change introduced by this patch.

This rewrites the IXP4xx CF (IDE) libata driver to use the
device tree exclusively to look up its resources:
- Probe exclusively from the device tree and look up all
resources from there.
- Allocate a local state container with devres and pass
this around in .private_data.
- Initialize with struct ata_port_info.
- Use the .set_piomode() callback instead of the much
wider .set_mode(), we only support PIO after all.
- Bump driver version number from 0.2 to 1.0 to reflect this
wider change.
- Get a handle on the expansion bus syscon regmap to alter
the timings on the chip select.
- Put in the more elaborate timing adjustment code for PIO0
to PIO4 in 8 and 16bit mode from the downstream OpenWrt
patch.
The board file initialization path and platform data include
is dropped because the board files will be deleted at the same
time as this patch is merged.
The platform data file is not deleted right now so as not to
conflict with the removal of board files.

Portable drivers cannot use mach/platform.h, so move the
structure into its own header. With this, compile testing
can be enabled.

Multiple users report that they need to disable DMA on this driver,
so provide an option to do so without affecting all of libata.

In order to create a proper PCI driver for the IXP4xx
we need to make the old PCI driver and its reliance
on <mach/io.h> optional.
Create a new Kconfig symbol for the legacy PCI driver
IXP4XX_PCI_LEGACY and only activate NEED_MACH_IO_H
for this driver.
A few files need to be adjusted to explicitly include
the <mach/hardware.h> and <mach/cpu.h> headers that
they previously obtained implicitly using <linux/io.h>
that would include <mach/io.h> and in turn include
these two headers.
This breaks our reliance on the old PCI and indirect
PCI support so we can reimplement a proper purely
DT-based driver in the PCI subsystem.
