bf6263a853 [libata] Use ATA_UDMAx standard masks when filling driver's udma_mask info
The ATA_UDMAx masks are self-documenting, and far better than manually
writing in the hex mask.

Note that pata_it8213 mask differed from the comment.  Added a FIXME there.

4447d35156 libata: convert the remaining SATA drivers to new init model
Convert ahci, sata_sil, sata_sil24, sata_svw, sata_qstor, sata_mv,
sata_sx4, sata_vsc and sata_inic162x to new init model.

Now that host and ap are available during intialization, functions are
converted to take either host or ap instead of low level parameters
which were inevitable for functions shared between init and other
paths.  This simplifies code quite a bit.

* init_one()'s now follow more consistent init order

* ahci_setup_port() and ahci_host_init() collapsed into
  ahci_init_one() for init order consistency

* sata_vsc uses port_info instead of setting fields manually

* in sata_svw, k2_board_info converted to port_info (info is now in
  port flags).  port number is honored now.

Tested on ICH7/8 AHCI, jmb360, sil3112, 3114, 3124 and 3132.

246ce3b675 libata: add another IRQ calls (libata drivers)
This patch is against each libata driver.

Two IRQ calls are added in ata_port_operations.
- irq_on() is used to enable interrupts.
- irq_ack() is used to acknowledge a device interrupt.

In most drivers, ata_irq_on() and ata_irq_ack() are used for
irq_on and irq_ack respectively.

In some drivers (ex: ahci, sata_sil24) which cannot use them
as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

0d5ff56677 libata: convert to iomap
Convert libata core layer and LLDs to use iomap.

* managed iomap is used.  Pointer to pcim_iomap_table() is cached at
  host->iomap and used through out LLDs.  This basically replaces
  host->mmio_base.

* if possible, pcim_iomap_regions() is used

Most iomap operation conversions are taken from Jeff Garzik
<jgarzik@pobox.com>'s iomap branch.

24dc5f33ea libata: update libata LLDs to use devres
Update libata LLDs to use devres.  Core layer is already converted to
support managed LLDs.  This patch simplifies initialization and fixes
many resource related bugs in init failure and detach path.  For
example, all converted drivers now handle ata_device_add() failure
gracefully without excessive resource rollback code.

As most resources are released automatically on driver detach, many
drivers don't need or can do with much simpler ->{port|host}_stop().
In general, stop callbacks are need iff port or host needs to be given
commands to shut it down.  Note that freezing is enough in many cases
and ports are automatically frozen before being detached.

850a9d8a8b [libata] sata_svw, sata_vsc: kill iomem warnings
Now that iomap merge is close to reality, and since the warnings and
issue have been around so long, we don't need a reminder on every build
that libata needs to be converted over to iomap.

c10340aca2 [libata] sata_svw: Disable ATAPI DMA on current boards (errata workaround)
Current Broadcom/Serverworks SATA boards (including Apple K2 SATA)
have problems with ATAPI DMA, so it is disabled.  ATAPI PIO, ATA PIO,
and ATA DMA continue to work just fine.

cca3974e48 libata: Grand renaming.
The biggest change is that ata_host_set is renamed to ata_host.

* ata_host_set			=> ata_host
* ata_probe_ent->host_flags	=> ata_probe_ent->port_flags
* ata_probe_ent->host_set_flags	=> ata_probe_ent->_host_flags
* ata_host_stats		=> ata_port_stats
* ata_port->host		=> ata_port->scsi_host
* ata_port->host_set		=> ata_port->host
* ata_port_info->host_flags	=> ata_port_info->flags
* ata_(.*)host_set(.*)\(\)	=> ata_\1host\2()

The leading underscore in ata_probe_ent->_host_flags is to avoid
reusing ->host_flags for different purpose.  Currently, the only user
of the field is libata-bmdma.c and probe_ent itself is scheduled to be
removed.

ata_port->host is reused for different purpose but this field is used
inside libata core proper and of different type.
