      libata: implement protocol tests · 405e66b3
      Tejun Heo authored 
      Implement protocol tests - ata_is_atapi(), ata_is_nodata(),
ata_is_pio(), ata_is_dma(), ata_is_ncq() and ata_is_data() and use
them to replace is_atapi_taskfile() and hard coded protocol tests.

      libata: rearrange ATA_DFLAG_* · f20ded38
      Tejun Heo authored 
      Area for DFLAGs which are cleared on INIT is full.  Extend it by 8
bits.

      ahci: update PCS programming · 49f29090
      Tejun Heo authored 
      For intel ones, ahci unconditionally OR'd 0xf to PCS.  This isn't
correct for the following cases.

* ich6/7m's which only implement P0 and P2 (0xf works fine tho)

* ich8/9's which have six ports and needs 0x3f to enable all ports

This patch updates PCS programming such that...

* port_map determined by ahci_save_initial_config() is OR'd instead of 0xf

* PCS is updated only if necessary (there are turned off enable bits)

port_map is determined from PORTS_IMPL PCI register which is
implemented as write or write-once register.  If the register isn't
programmed, ahci automatically generates it from number of ports,
which is good enough for PCS programming.  ICH6/7M are probably the
only ones where non-contiguous enable bits are necessary && PORTS_IMPL
isn't programmed properly but they're proven to work reliably with 0xf
anyway.

      pata_ninja32: Cardbus ATA initial support · 51dbd490
      Alan Cox authored 
      Lots of work needed to bring it up to scratch but it does work so you can
now use the card. That makes it at least useful, especially as the other
cardbus cards are usually INIC162x which aren't yet supported well.

      libata-sff: tf_load · 76548eda
      Alan Cox authored 
      Jeff said he preferred that the SFF tf_load followed the spec and we
documented that anyone who needed different overrode it, rather than it
using the ->check_status methods. No driver relies on the current behaviour.

      libata: IORDY handling · b9f8ab2d
      Alan Cox authored 
      I believe this version meets all Sergei's objections

Correct the logic for when we issue a set features for transfer mode

- If the device has IORDY and the controller has IORDY - set the mode
- If the device has IORDY and the controller does not - turn IORDY off
- If neither has IORDY do nothing

      libata-acpi: add ACPI _PSx method · bd3adca5
      Shaohua Li authored 
      ACPI spec (ver 3.0a, p289) requires IDE power on/off executes ACPI _PSx
methods. As recently most PATA drivers use libata, this patch adds _PSx
method support in libata. ACPI spec doesn't mention if SATA requires the
same _PSx method.

      libata: Disable ATA8-ACS proposed Trusted Computing features by default · ae8d4ee7
      Alan Cox authored 
      Historically word 48 in the identify data was used to mean 32bit I/O
was supported for VLB IDE etc. ATA8 reassigns this word to the Trusted
Computing Group, where it is used for TCG features. This means that
an ATA8 TCG drive is going to trigger 32bit I/O on some systems which
will be funny.

Anyway we need to sort this out ready for ATA8 so:
- Reorder the ata.h header a bit so the ata_version function occurs early
  in it
- Make dword_io check the ATA version
- Add an ATA8 version checking TCG presence test

While we are at it the current drafts have a flaw where it may not be
possible to disable TCG features at boot (and opt out of the trusted
model) as TCG intends because it relies on presence of a different
optional feature (DCS). Handle this in software by refusing the TCG
commands if libata.allow_tpm is not set. (We must make it possible
as some environments such as proprietary VDR devices will doubtless
want to use it to lock up content)

Finally as with CPRM print a warning so that the user knows they may
not be able to full access and use the device.
