As we read out the manufactor and card_id from the PCMCIA device in the
PCMCIA core, and device drivers can access those reliably in struct
pcmcia_device's fields manf_id and card_id, remove additional (and partly
broken) manf_id and card_id detection logic from PCMCIA device drivers.

Switch to pci_get_bus_and_slot because some x86 systems seem to be
handing us a device with dev->bus = NULL. Also don't apply the isa fixup
to revision C6 and later of the chip.
Really we need to work out wtf is handing us pdev->bus = NULL, but firstly
and more importantly we need the drivers working.

This patch adds code to fix up the PHYMODE4 "align timing"
register value on second-generation Promise SATA chips.
Failure to correct this value on non-x86 machines makes
drive detection prone to failure due to timeouts. (I've
observed about 50% detection failure rates on SPARC64.)
The HW boots with a bad value in this register, but on x86
machines the Promise BIOS corrects it to the value recommended
by the manual, so most people have been unaffected by this issue.
After developing the patch I checked Promise's SATAII driver,
and discovered that it also corrects PHYMODE4 just like this
patch does.
This patch depends on the sata_promise SATAII updates
patch I sent recently.

libata switched to IRQ-driven IDENTIFY when IRQ-driven PIO was
introduced. This has caused a lot of problems including device
misdetection and phantom device.
ATA_FLAG_DETECT_POLLING was added recently to selectively use polling
IDENTIFY on problemetic drivers but many controllers and devices are
affected by this problem and trying to adding ATA_FLAG_DETECT_POLLING
for each such case is diffcult and not very rewarding.
This patch makes libata always use polling IDENTIFY. This is
consistent with libata's original behavior and drivers/ide's behavior.

ahci_init_controller() calls ahci_deinit_port() to make sure the
controller is stopped before initializing the controller. In turn,
ahci_deinit_port() invokes ahci_power_down() to power down the port.
If the controller supports slumber mode, the link is put into it.
Unfortunately, some devices don't implement link powersaving mode
properly and show erratic behavior after link is put into slumber
mode. For example, HL-DT-ST DVD-RAM GSA-H30N completely locks up on
slumber transition and can only be recovered with the *REAL* hard
reset - power removal and reapply.
Note that this makes the first probing reset different from all
others. If the above dvd-ram is hotplugged after ahci is initialized,
no problem occurs because ahci is already fully initialized with phy
powered up. So, this might also be the reason for other weird AHCI
initial probing abnormalities.
This patch moves power up/down out of port init/deinit and call them
only when needed.
Power down is now called only when suspending. As system suspend
usually involves powering down 12v for storage devices, this shouldn't
cause problem even if the attached device doesn't support slumber
mode. However, in partial power management and suspend failure cases,
devices might lock up after suspend attempt. I thought about removing
transition to slumber mode altogether but ahci spec mandates it before
HBA D3 state transition. Blacklisting such devices might be the
solution.

Now that BMDMA status is recorded in irq handler. ata_bmdma_freeze()
is free to manipulate host status. Under certain circumstances, some
controllers (ICH7 in enhanced mode w/ IRQ shared) raise IRQ when CTL
register is written to and ATA_NIEN doesn't mask it.
This patch makes ata_bmdma_freeze() clear all pending IRQs after
freezing a port. This change makes explicit clearing in
ata_device_add() unnecessary and thus kills it. The removed code was
SFF-specific and was in the wrong place.
Note that ->freeze() handler is always called under ap->lock held and
irq disabled. Even if CTL manipulation causes stuck IRQ, it's cleared
immediately. This should be safe (enough) even in SMP environment.
More correct solution is to mask the IRQ from IRQ controller but that
would be an overkill.

* READ CAPACITY (16) implementation fixed. Result was shifted by two
bytes. Carlos Pardo spotted this problem and submitted preliminary
patch. Capacity => 2TB is handled correctly now. (verifid w/ fake
capacity)
* Use dev->n_sectors instead of re-reading directly from ID data.
* Define and use ATA_SCSI_RBUF_SET() which considers rbuf length.
This should be done for all simulation functions. Userland can
issue any simulated command with arbitrary buffer length.

take #2
This patch implements ATA_FLAG_SETXFER_POLLING and use in pata_via.
If this flag is set, transfer mode setting performed by polling not by
interrupt. This should help those controllers which raise interrupt
before the command is actually complete on SETXFER.
Rationale for this approach.
* uses existing facility and relatively simple
* no busy sleep in the interrupt handler
* updating drivers is easy
While at it, kill now unused flag ATA_FLAG_SRST in pata_via.

There are machines out there which share legacy PCI IDE IRQs w/ other
devices. libata SFF interrupt/HSM code is ready for shared IRQ and
has been setting IRQF_SHARED for devices in native PCI mode. Device
in legacy mode is still a PCI device and thus supposedly uses
active-low level triggered IRQ.
Machines with such setup should be quite rare and w/o this flag libata
is likely to fail loading and render the system unuseable. Also, IDE
driver has been setting IRQF_SHARED for devices in legacy mode for a
looooong time.

The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv
with ATAPI devices on controllers running in ADMA mode. Some of the
logic in the nv_adma_bmdma_* functions was inverted causing a bunch of
warnings and caused those functions not to work properly. Also, when an
ATAPI device is connected, we need to use the legacy DMA engine. The
code now disables the PCI configuration register bits for ADMA so that
this works, and ensures that no ATAPI DMA commands go through until this
is done.

This patch updates the sata_promise driver as follows:
- Correct typo in definition of PDC_TBG_MODE: it's at 0x41C not 0x41
in first-generation chips. This error caused PCI access alignment
exceptions on SPARC64, and on all platforms it disabled the expected
initialisation of TBG mode.
- Add flags field to struct pdc_host_priv. Define PDC_FLAG_GEN_II
and use it to distinguish first- and second-generation chips.
- Prevent the FLASH_CTL FIFO_SHD bit from being set to 1 on second-
generation chips. This matches Promises' ulsata2 driver.
- Prevent TBG mode and SLEW rate initialisation in second-generation chips.
These two registers have moved, TBG mode has been redefined, and
Promise's ulsata2 driver no longer attempts to initialise them.
- Correct PCI device table so devices 0x3570, 0x3571, and 0x3d73 are
marked as 2057x (2nd gen) not 2037x (1st gen).
- Correct PCI device table so device 0x3d17 is marked as 40518
(2nd gen 4 ports) not 20319 (1st gen 4 ports).
- Correct pdc_ata_init_one() to treat 20771 as a second-generation chip.
Tested on 0x3d75 (2nd gen), 0x3d73 (2nd gen), and 0x3373 (1st gen) chips.
The information comes from the newly uploaded Promise SATA HW specs,
Promise's ultra and ulsata2 drivers, and debugging on 3d75/3d73/3373 chips.
hp->hotplug_offset could now be removed and its value recomputed
in pdc_host_init() using hp->flags, but that would be a cleanup
not a functional change, so I'm ignoring it for now.
