Subject: [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.

Subject: [PATCH] ata_piix: implement proper port map

Replace combined mode handling via PIIX_COMB/COMB_PATA_P0 with proper
port map.  PIIX now prints port configuration during initialization.
ATA_FLAG_SLAVE_POSS is now turned on for SATA ports only when the
slave device is actually avaliable.

Subject: [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.

Subject: [SCSI] libata: implement minimal transport template for
 ->eh_timed_out

SCSI midlayer has moved hostt->eh_timed_out to transport template.  As
libata doesn't need full-blown transport support yet, implement
minimal transport for libata.  No transport class or whatsoever, just
empty transport template with ->eh_timed_out hook.
