Tejun Heo ccc4672aff [PATCH] ata_piix: convert ata_piix to new probing mechanism
Convert ata_piix to new probing mechanism.  Automatic hotplug is not
supported due to hardware limitation (no PHY event interrupt), but
warm plugging works.

Christoph Hellwig 9227c33de8 [PATCH] move ->eh_strategy_handler to the transport class
Overriding the whole EH code is a per-transport, not per-host thing.
Move ->eh_strategy_handler to the transport class, same as
->eh_timed_out.

Downside is that scsi_host_alloc can't check for the total lack of EH
anymore, but the transition period from old EH where we needed it is
long gone already.

Tejun Heo d133ecab8f [PATCH] ata_piix: reimplement piix_sata_probe()
Reimplement piix_sata_probe() such that it turns on PCS enable bits on
all avaliable ports and check present bits after a while to determine
device presence.  This should help broken BIOSes.  After device
presence detection is complete, PCS enable bits of unoccupied bits are
turned off unless the controller supports AHCI (ICH6/7 docs mandate
all enables bits are always set on AHCI capable controllers).

Note that PCS present bits are ignored on 6300ESB as described in the
datasheet.  This should fix device detection problems reported with
the controller.

Tejun Heo ff0fc1467f [PATCH] ata_piix: fix MAP VALUE interpretation for for ICH6/7
Unlike their older siblings, ICH6 and 7 use different scheme for MAP
VALUE.  This patch makes ata_piix interpret MV properly on ICH6/7.

Pre-ICH6/7

 The value of these bits indicate the address range the SATA port
 responds to, and whether or not the SATA and IDE functions are
 combined.

 000 = Non-combined. P0 is primary master. P1 is secondary master.
 001 = Non-combined. P0 is secondary master. P1 is primary master.
 100 = Combined. P0 is primary master. P1 is primary slave. P-ATA is
       2:0 Map Value secondary.
 101 = Combined. P0 is primary slave. P1 is primary master. P-ATA is
       secondary.
 110 = Combined. P-ATA is primary. P0 is secondary master. P1 is
       secondary slave.
 111 = Combined. P-ATA is primary. P0 is secondary slave. P1 is
       secondary master.

ICH6/7

 Map Value - R/W. Map Value (MV): The value in the bits below indicate
the address range the SATA ports responds to, and whether or not the
PATA and SATA functions are combined. When in combined mode, the AHCI
memory space is not available and AHCI may not be used.

 00 = Non-combined. P0 is primary master, P2 is the primary slave. P1
      is secondary master, P3 is the 1:0 secondary slave (desktop
      only). P0 is primary master, P2 is the primary slave (mobile
      only).
 01 = Combined. IDE is primary. P1 is secondary master, P3 is the
      secondary slave. (desktop only)
 10 = Combined. P0 is primary master. P2 is primary slave. IDE is secondary
 11 = Reserved

Jeff, without this patch, ata_piix misdetects my ICH7's combined mode,
ending up not applying bridge limits to PX-710SA and configuring IDE
drive on 40-c cable to UDMA/66.

Jens Axboe 9b84754866 [PATCH] Suspend support for libata
This patch adds suspend patch to libata, and ata_piix in particular. For
most low level drivers, they should just need to add the 4 hooks to
work. As I can only test ata_piix, I didn't enable it for more
though.

Suspend support is the single most important feature on a notebook, and
most new notebooks have sata drives. It's quite embarrassing that we
_still_ do not support this. Right now, it's perfectly possible to
suspend the drive in mid-transfer.

Hannes Reinecke 6a690df5c8 [PATCH] scan all enabled ports on ata_piix
ICH6 spec defines the PORT_ bits as:

PORT_ENABLED (R/W):

  0 = Disabled.  The port is in the off state and cannot detect any
  devices.

  1 = Enabled.  The port can transition between the on, partial, and
  slumber states and can detect devices.

PORT_PRESENT  (R/O)

  The status of this bit may change at any time.  This bit is cleared
  when the port is disabled via PORT_ENABLED.  This bit is not cleared upon
  surprise removal of a device.

So from a textual view it is not necessary that PORT_PRESENT _must_ be set,
especially if a device detection has to be done anyway.  And, in fact, this
is the view that ACER has been taken with its new Laptops (e.g.  Travelmate
4150).

And the definition of PORT_ENABLED / PORT_PRESENT is mixed up, btw.
