When the sata_mv driver is used as a platform driver,
mv_create_dma_pools() is never called so it fails when trying
to alloc in mv_pool_start().

Forcibly set more of the configuration at init time. This seems to fix at
least one problem reported. We don't know what most of these bits do, but
we do know what windows stuffs there.

Some controllers (VIA CX700) raise device error on SETXFER even after
mode configuration succeeded. Update ata_dev_set_mode() such that
device error is ignored if transfer mode is configured correctly. To
implement this, device is revalidated even after device error on
SETXFER.
This fixes kernel bugzilla bug 8563.

Maybe for the trivial tree...
sata_via.c has PATA support since:
d73f30e1c9
sata_via: PATA support
AFAICS so the TODO list is no longer true.

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.

qc->n_iter was used for libata's own sg walking before sg chaining
replaced it. During conversion, the field and its usage in sata_fsl
were left behind. Kill the filed and update sata_fsl.

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.
