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.

Thanks.

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.

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.

7b6dbd6872 libata: Check PCI sub-class code before disabling AHCI
This patch adds functionality to check the PCI sub-class code of an
AHCI capable device before disabling AHCI.  It fixes a bug where an
ICH7 sata controller is being setup by the BIOS as sub-class 1 (ide)
and the AHCI control registers weren't being initialized, thus causing
an IO error in piix_disable_ahci().

aa8f0dc6c3 libata: Fix use-after-iounmap
Jens Axboe pointed out that the iounmap() call in libata was occurring
too early, and some drivers (ahci, probably others) were using ioremap'd
memory after it had been unmapped.

The patch should address that problem by way of improving the libata
driver API:

* move ->host_stop() call after all ->port_stop() calls have occurred.

* create default helper function ata_host_stop(), and move iounmap()
call there.

* add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark).
sata_qstor appears to require the host-stop-before-port-stop ordering
that existed prior to applying the attached patch.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
