The sata_mv driver can be loaded as a platform device, as is done by
various Orion (ARM) based devices. The driver needs to define a module
alias for the platform driver so udev will load it automatically.
Tested with Debian on a QNAP TS-209.

Use ld_qdi and ld_winbond to avoid shadowing static int
variables qdi and winbond. The ld_ prefix refers to
legacy_data.

This just updates the libata slave configure routine to take advantage
of the block layer drain buffers. It also adjusts the size lengths in
the atapi code to add the drain buffer to the DMA length so the driver
knows it can rely on it.
I suspect I should also be checking for AHCI as well as ATA_DEV_ATAPI,
but I couldn't see how to do that easily.
tj: * atapi_drain_needed() added such that draining is applied to only
misc ATAPI commands.
* q->bounce_gfp used when allocating drain buffer.
* Now duplicate ATAPI PIO drain logic dropped.
* ata_dev_printk() used instead of sdev_printk().

that provided by the block layer
ATA requires that all DMA transfers begin and end on word boundaries.
Because of this, a large amount of machinery grew up in ide to adjust
scatterlists on this basis. However, as of 2.5, the block layer has a
dma_alignment variable which ensures both the beginning and length of a
DMA transfer are aligned on the dma_alignment boundary. Although the
block layer does adjust the beginning of the transfer to ensure this
happens, it doesn't actually adjust the length, it merely makes sure
that space is allocated for transfers beyond the declared length. The
upshot of this is that scatterlists may be padded to any size between
the actual length and the length adjusted to the dma_alignment safely
knowing that memory is allocated in this region.
Right at the moment, SCSI takes the default dma_aligment which is on a
512 byte boundary. Note that this aligment only applies to transfers
coming in from user space. However, since all kernel allocations are
automatically aligned on a minimum of 32 byte boundaries, it is safe to
adjust them in this manner as well.
tj: * Adjusting sg after padding is done in block layer. Make libata
set queue alignment correctly for ATAPI devices and drop broken
sg mangling from ata_sg_setup().
* Use request->raw_data_len for ATAPI transfer chunk size.
* Killed qc->raw_nbytes.
* Separated out killing qc->n_iter.

For misc ATAPI commands which transfer variable length data to the
host, overflow can occur due to application or hardware bug. Such
overflows can be ignored safely as long as overflow data is properly
drained. libata HSM implementation has this implemented in
__atapi_pio_bytes() and recently updated for 2.6.24-rc but it requires
further improvements. Improve drain logic such that...
* Report overflow errors using ehi desc mechanism instead of printing
directly.
* Properly calculate the number of bytes to be drained considering
actual number of consumed bytes for partial draining.

This fixes some problems with ATAPI devices on nForce4 controllers in ADMA mode
on systems with memory located above 4GB. We need to delay setting the 64-bit
DMA mask until the PRD table and padding buffer are allocated so that they don't
get allocated above 4GB and break legacy mode (which is needed for ATAPI
devices). Also, if either port is in ATAPI mode we need to set the DMA mask
for the PCI device to 32-bit to ensure that the IOMMU code properly bounces
requests above 4GB, as it appears setting the bounce limit does not guarantee
that we will not try to map requests above this point.

AHCI uses CAP.NP to indicate the number of ports and PI to tell which
ports are enabled. The only requirement is that the number of ports
indicated by CAP.NP should equal or be higher than the number of
enabled ports in PI.
CAP.NP and PI carry duplicate information and there have been some
interesting cases. Some early AHCI controllers didn't set PI at all
and just implement from port 0 to CAP.NP. An ICH8 board which wired
four out of six available ports had 3 (4 ports) for CAP.NP and 0x33
for PI. While ESB2 has less bits set in PI than the value in CAP.NP.
Till now, ahci driver assumed that PI is invalid if it doesn't match
CAP.NP exactly. This violates AHCI standard and the driver ends up
accessing unmimplemented ports on ESB2.
This patch updates CAP.NP and PI handling such that PI can have less
number of bits set than indicated in CAP.NP and the highest port is
determined as the maximum port of what CAP.NP and PI indicate.

This patch converts users of pci_enable_device_bars() to the new
pci_enable_device_{io,mem} interface.
The new API fits nicely, except maybe for the QLA case where a bit of
code re-organization might be a good idea but I prefer sticking to the
simple patch as I don't have hardware to test on.
I'll also need some feedback on the cs5520 change.

This patch is based on an original patch from Kuan Luo of NVIDIA,
posted under subject "fixed a bug of adma in rhel4u5 with HDS7250SASUN500G".
His description follows. I've reworked it a bit to avoid some unnecessary
repeated checks but it should be functionally identical.
"The patch is to solve the error message "ata1: CPB flags CMD err,
flags=0x11" when testing HDS7250SASUN500G in rhel4u5.
I tested this hd in 2.6.24-rc7 which needed to remove the mask in
blacklist to run the ncq and the same error also showed up.
I traced the bug and found that the interrupt finished a command (for
example, tag=0) when the driver got that adma status is
NV_ADMA_STAT_DONE and cpb->resp_flags is NV_CPB_RESP_DONE.
However, For this hd, the drive maybe didn't clear bit 0 at this moment.
It meaned the hardware had not completely finished the command.
If at the same time the driver freed the command(tag 0) and sended
another command (tag 0), the error happened.
The notifier register is 32-bit register containing notifier value.
Value is bit vector containing one bit per tag number (0-31) in
corresponding bit positions (bit 0 is for tag 0, etc). When bit is set
then ADMA indicates that command with corresponding tag number completed
execution.
So i added the check notifier code. Sometimes i saw that the notifier
reg set some bits , but the adma status set NV_ADMA_STAT_CMD_COMPLETE
,not NV_ADMA_STAT_DONE. So i added the NV_ADMA_STAT_CMD_COMPLETE check
code."

The integrated SATA controller is connected directly to the SoC's
internal bus, not via PCI interface. this patch removes the dependency
on the PCI interface.
