Bartlomiej Zolnierkiewicz 4db90a1452 ide: add IDE_HFLAG_ABUSE_SET_DMA_MODE host flag
* Add IDE_HFLAG_ABUSE_SET_DMA_MODE host flag and use it to decide
  what to do with transfer modes < XFER_PIO_0 in ide_set_xfer_rate().

* Set IDE_HFLAG_ABUSE_SET_DMA_MODE in host drivers that need it
  (aec62xx, amd74xx, cs5520, cs5535, hpt34x, hpt366, pdc202xx_old,
  serverworks, tc86c001 and via82cxxx) and cleanup ->set_dma_mode
  methods in host drivers that don't (IDE core code guarantees that
  ->set_dma_mode will be called only for modes which are present
  in SWDMA/MWDMA/UDMA masks).

While at it:

* Add IDE_HFLAGS_HPT34X/HPT3XX/PDC202XX/SVWKS define in
  hpt34x/hpt366/pdc202xx_old/serverworks host driver.

There should be no functionality changes caused by this patch.

Aleksandar Radovanovic b48d08177f aec62xx: Fix kernel oops in driver's probe function
Add pci_enable_device() to aec62xx probe function
before doing any I/O.

Original probe function tries to read from device's
PCI region 4 before calling ide_setup_pci_device().
Since the device is not enabled at this point,
on machines that have no firmware PCI initialization
(e.g. ASUS WL-700gE router), corresponding PCI BAR 
is 0 and the following inb() causes a kernel oops.

Bartlomiej Zolnierkiewicz 85ad93ad56 ide: set drive->autotune in ide_pci_setup_ports()
Majority of host drivers using IDE PCI layer set drive->autotune, the only
exceptions are:

generic.c
ns87415.c
rz1000.c
trm290.c
* no ->set_pio_mode method

it821x.c:
* if memory allocation fails drive->autotune won't be set
  (but there also won't be ->set_pio_mode method in such case)

piix.c:
* MPIIX controller (no ->init_hwif method so also no ->set_pio_mode method)

However if there is no ->set_pio_mode method there are no changes in behavior
w.r.t. PIO tuning so always set drive->autotune in ide_pci_setup_ports().

  the host for the transfer mode after programming the device.  Set it
  in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac
  and via82cxxx host drivers.

* Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely
  skip programming of host/device for the transfer mode ("smart" hosts).
  Set it in it821x host driver and check it in ide_tune_dma().

* Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all
  direct ->set_pio_mode/->speedproc users to use these helpers.

* Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc
  methods to callers.

* Rename ->speedproc method to ->set_dma_mode, make it void and update
  all implementations accordingly.

* Update ide_set_xfer_rate() comments.

* Unexport ide_config_drive_speed().

v2:
* Fix issues noticed by Sergei:
  - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt
    to setting DMA modes from sc1200_set_pio_mode() to do_special()
  - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma()
  - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode()
  - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode()
  - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL
  - don't set ->set_{pio,dma}_mode on it821x in "smart" mode
  - fix build problem in pmac.c
  - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c

- HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change
  PIO mode if it821x controller is in "smart" mode
- removal of two debugging printk-s (from cs5530.c and sc1200.c)
- transfer modes 0x00-0x07 passed from user space may be programmed twice on
  the device (not really an issue since 0x00 is not supported correctly by
  any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid)

Sergei Shtylyov 826a1b6502 aec62xx: fix PIO/DMA setup issues
Teach the driver's tuneproc() method to do PIO auto-runing properly since it
treated 5 instead of 255 as auto-tune request, and also passed the mode limit
of PIO5 to ide_get_best_pio_mode() despite supporting up to PIO4 only.

While at it, also:

- remove the driver's wrong claim about supporting SWDMA modes;

- stop hooking ide_dma_timeout() method as the handler clearly doesn't fit for
  the task...

Bartlomiej Zolnierkiewicz 7569e8dc22 ide: add ide_use_fast_pio() helper (v3)
* add ide_use_fast_pio() helper for use by host drivers

* add DMA capability and hwif->autodma checks to ide_use_dma()

  - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1)

    [ for the IT8211/2 in SMART mode this check shouldn't be made but since
      in it821x_fixups() we set DMA bit explicitly:

               if(strstr(id->model, "Integrated Technology Express")) {
                       /* In raid mode the ident block is slightly buggy
                          We need to set the bits so that the IDE layer knows
                          LBA28. LBA48 and DMA ar valid */
                       id->capability |= 3;            /* LBA28, DMA */

       we are better off using generic helper if we can ]

  - ide-cris driver didn't set ->autodma

    [ before the patch hwif->autodma was only checked in the chipset specific
      hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check()
      function so there no behavior change here ]

v2:
* updated patch description (thanks to Alan Cox for the feedback)

Alan Cox 28a2a3f587 [PATCH] Fix 2.6.18-rc6 IDE breakage, add missing ident needed for current VIA boards
There are two changes here.  The first reverses the broken PCI_DEVICE
conversion back to the old format.  The second adds a missing PCI ID so
you can actually boot 2.6.18 on 2 month old VIA motherboards (right now
only 2.6.18-mm works).

CC'd to Jeff to check the PCI ident but its a) in several distro kernels
and b) in 2.6.18-mm [twice ??]

Move auto arrays to static (const).  Clean up using PCI_DEVICE in places,

Fix the serverworks cable detect logic (if ordering is wrong).  Backport
from libata.  Plenty of scope for more cleanup left.

This patch adds missing initialization sequence, necessary to get the
"Macintosh" version of AEC6280 cards to work in Linux.  Without this patch,
the driver hangs for several minutes trying to initialize the card and the
kernel is left in an unstable state.  This patch has been tested fine on
ppc and i386.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
