* Rename ide-cd kernel module to ide-cd_mod in preparation to moving code out

* Move VERBOSE_IDE_CD_ERRORS code from ide-cd.[c,h] to ide-cd_verbose.c.
ide-cd_verbose.c is IDE subsystem independent and may be easily converted
into generic library usable by other drivers (i.e. libata) if needed.
* Add CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS config option to drivers/ide/Kconfig
replacing VERBOSE_IDE_CD_ERRORS define. Make this config option enabled by

* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c
file for probing PCI host drivers registered with IDE core (special case

the ordering in which all IDE host drivers are probed when IDE is built-in
during link time.
* Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch
specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris
arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific).
* Move probing of ide-cris (cris arch specific) host driver before cmd640

* Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends
on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300
(h8300 arch specific).
* Add "probe_vlb" kernel parameter to cmd640 host driver and update
Documentation/ide.txt accordingly.

This is now very similar to pata_platform.c, they both use
same platform data structure and same resources.
To achieve that, byte_lanes_swapping platform data variable
and platform specified iops removed from that driver. It's fine,
since those were never used anyway.
pata_platform and ide_platform are carrying same driver names,
to easily switch between these drivers, without need to touch

IDE PCI host drivers should register themselves with IDE core only when
IDE driver is built-in, otherwise (IDE driver is modular and thus IDE PCI
host drivers are also modular) the code has no effect and just complicates
the probing.
Fix it by adding new config option CONFIG_IDEPCI_PCIBUS (defined only when
needed and invisible to the user) and covering by #ifdef/#endif the code
in question. It turned out that "ide=reverse" was silently accepted but did

All modern distributions have been setting these options to "y" for ages.
(additionally "n" cases have been obsoleted for few years). Therefore use
DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer
needed CONFIG_IDEDMA_AUTO). This fixes DMA support for rare configurations
where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used
to enable DMA support and which were forced to PIO mode by "ide: don't allow
DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch. There is no
functionality loss because "ide=nodma" kernel option is still available.

We use a drivers/ide driver because its design is more suitable for
SCC IDE controller than libata driver. Since SCC supports only 32bit
read/write, we must override many callbacks of ata_port_operations
by modifying generic helpers. Each time the libata common code is
updated, we must update those modified helpers. It is very hard for us.
But we will try to implement the libata driver as needed.

This patch implements ACPI integration for generic IDE devices.
The ACPI spec mandates that some methods are called during suspend and
resume. And consequently there most modern Laptops cannot resume
properly without it.
According to the spec, we should call '_GTM' (Get Timing) upon suspend
to store the current IDE adapter settings.
Upon resume we should call '_STM' (Set Timing) to initialize the
adapter with the stored settings; afterwards '_GTF' (Get Taskfile)
should be called which returns a buffer with some IDE initialisation
commands. Those commands should be passed to the drive.
There are two module params which control the behaviour of this patch:
'ide=noacpi'
Do not call any ACPI methods (Disables any ACPI method calls)
'ide=acpigtf'
Enable execution of _GTF methods upon resume.
Has no effect if 'ide=noacpi' is set.
'ide=acpionboot'
Enable execution of ACPI methods during boot.
This might be required on some machines if 'ide=acpigtf' is
selected as some machines modify the _GTF information
depending on the drive identification passed down with _STM.

Bart, here's a driver I've been keeping out-of-tree for the past couple
of years. This is for the Delking/Lexar/ASKA/etc.. 32-bit cardbus IDE
CompactFlash adapter card.
It's probably way out of sync with the latest driver model (??), but it
still builds/works. I'm not interested in doing much of a rewrite, other
than for libata someday, as I no longer use the card myself.
But lots of other people do seem to use it, so it might be nice to see it
"in-tree".

This is the driver for the Toshiba TC86C001 GOKU-S PCI IDE controller,
completely reworked from the original brain-damaged Toshiba's 2.4 version.
This single channel UltraDMA/66 controller is very simple in programming,
yet Toshiba managed to plant many interesting bugs in it. The particularly
nasty "limitation 5" (as they call the errata) caused me to abuse the IDE
core in a possibly most interesting way so far. However, this is still
better than the #ifdef mess in drivers/ide/ide-io.c that the original
version included (well, it had much more mess)...
