If ->dma_base is not set (== PCI BAR4 cannot be reserved) then DMA hooks
shouldn't be initialized or bad things will happen.

Devices which don't set word 93 validation bit should be now handled by
ide-iops.c::ivb_list[] and for debugging purposes cable detection can be
completely overriden with "idex=ata66" parameter.

Need to probe slave device first to make it release PDIAG-
(this is required for correct device side cable detection).
Based on libata commit f31f0cc2f0b7527072d94d02da332d9bb8d7d94c.
Thanks to Craig for testing this patch.

* Convert {ide_hwif_t,ide_pci_device_t}->host_flag to be u16.
* Add IDE_HFLAG_POST_SET_MODE host flag to indicate the need to program
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
- improve patch description
Changes in behavior caused by this patch:
- 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)

set on the device by ide-proc.c::set_xfer_rate()) and remove redundant
setting of ->{init,current}_speed.

* Add "good DMA drives" hack for icside to ide-dma.c::ide_find_dma_mode()
(in the long-term it should be either removed or generalized for all hosts).
* Use ide_tune_dma() in icside.c::icside_dma_check().
This results in the following changes in behavior:
- pre-EIDE SWDMA modes are now also respected
- drive->autodma is checked instead of hwif->autodma
(doesn't really matter as icside sets both to "1")
* Make ide-dma.c::__ide_dma_good_drive() static and drop "__" prefix.

* Add missing initialization of hwif->autodma and drive->autodma to
pmac_ide_setup_dma().
* Use ide_tune_dma() in pmac_ide_dma_check().
While at it:
* Fix pmac_ide_dma_check() return value if DMA mode is not programmed
(should be "-1" otherwise ide_set_dma() will try to enable DMA).
* Remove unnecessary drive->using_dma fiddling (->dma_off_quietly is always
called before ide_set_dma() call and ide_set_dma() calls ->ide_dma_on if
->ide_dma_check returns "0").
v2:
* No reason to blacklist all ide_floppy devices and the old code was always
enabling DMA anyway (without even programming controller/device if the
device was ide_floppy).

Use ide_config_drive_speed() instead of pmac_ide_do_setfeature() and remove
the latter, also ide-iops.c::__ide_wait_stat() could be static again.
Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's
->quirk_list is always zero and ->ide_dma_host_{on,off} are nops than
the only changes in behavior are:
* if PIO mode is set then ->dma_off_queitly is called to disable DMA
* if setting transfer mode fails ide_dump_status() is called to dump status
v2:
* IDE PMAC controllers allow separate PIO and DMA timings and PPC userland
depends on this fact, and calls "hdparm -p" without calling "hdparm -d".
Therefore to compensate for DMA being disabled by ide_config_drive_speed()
for PIO modes:
- add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver
- add handling of the new flag to ide-io.c::do_special()

Don't check for good device status before executing the command in

* Split off checking of the status register from ide_wait_stat() to
__ide_wait_stat() helper.
* Use the new helper in ide_config_drive_speed(). The only change in the
functionality is that the function now fails if after 20 sec (WAIT_CMD)
device is still busy (BUSY_STAT bit is set) while previously instead of
failing the function continued with checking for the correct device status
(which would give the device additional 10 usec to clear BUSY_STAT bit).
* Remove stale comment for ide_config_drive_speed().
* Remove duplicate comment for ide_wait_stat() from <linux/ide.h>.

Avoid creating P2P prefetch window for expansion ROMs
Because of the future possibility that P2P prefetch windows will contain
address ranges above 4GB some BIOSes are providing space in the P2P
non-prefetch windows for expansion ROMs. This is due to expansion ROM
BAR 32-bit limitation. When expansion ROM BARs without BIOS assigned
address(es) are currently found behind a P2P bridge, the kernel attempts
to create a P2P prefetch window for them even though space for them has
already been provided in the non-prefetch window. _CRS on some systems
with certain resource conservation conscious BIOSes may not provide the
extra 1MB or more memory resource needed for the expansion ROM motivated
prefetch window causing resource allocation errors.
This change corrects the problem by removing IORESOURCE_PREFETCH from
the expansion ROM flags initialization. It also removes
IORESOURCE_CACHEABLE which seems inappropriate if only non-cacheable
memory is available.

Skip ISA ioresource alignment on some systems
To conserve limited PCI i/o resource on some IBM multi-node systems, the
BIOS allocates (via _CRS) and expects the kernel to use addresses in
ranges currently excluded by pcibios_align_resource() [i386/pci/i386.c].
This change allows the kernel to use the currently excluded address
ranges on the IBM x3800, x3850, and x3950.

Remove transparent bridge sizing.
Due to code in pci_read_bridge_bases() [drivers/pci/probe.c] the child
bus of a transparent bridge already has access to the parent bus
resources so transparent bridge sizing appears unnecessary. The bridge
sizing includes alignment and granularity adjustments that can cause
significantly more memory to be reserved from the parant bus than
required by devices on the child bus and allotted by _CRS.
