acfad6e186 ide: add CONFIG_IDE_H8300 config option
Add a separate config option for ide-8300 host driver instead of depending
on CONFIG_H8300.

This change is a preparation for the future changes and also allows ide-h8300

8cb1f567f4 ide: Platform IDE driver
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

6d208b39c4 ide: legacy PCI bus order probing fixes
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
nothing in case when IDE driver was modular, this is fixed now.

120b9cfddf ide: remove CONFIG_IDEDMA_{ICS,PCI}_AUTO config options
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.

bde18a2e1e drivers/ide: PATA driver for Celleb
This is the patch (based on 2.6.19-rc4) for PATA controller of
Toshiba Cell reference set(Celleb). The reference set consists
of Cell, 512MB memory, Super Companion Chip(SCC) and some
peripherals such as HDD, GbE, etc. You can see brief explanation
and picture of Cell reference set at following URLs.

    http://www.toshiba.co.jp/about/press/2005_09/pr2001.htm
    http://cell-industries.com/toshiba_announces.php

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.

e3a59b4d93 ACPI support for IDE devices
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)...

bbb3bbdb0f [PATCH] non-libata driver for Jmicron devices
Less functional than libata this just uses the merged interface provided for
dumb legacy OS's.  This is basically a bridge for people not yet ready to use
libata for some reason or another.

Port visibility is entirely dependant on the BIOS setup.

9361401eb7 [PATCH] BLOCK: Make it possible to disable the block layer [try #6]
Make it possible to disable the block layer.  Not all embedded devices require
it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require
the block layer to be present.

This patch does the following:

 (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev
     support.

 (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls
     an item that uses the block layer.  This includes:

     (*) Block I/O tracing.

     (*) Disk partition code.

     (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.

     (*) The SCSI layer.  As far as I can tell, even SCSI chardevs use the
     	 block layer to do scheduling.  Some drivers that use SCSI facilities -
     	 such as USB storage - end up disabled indirectly from this.

     (*) Various block-based device drivers, such as IDE and the old CDROM
     	 drivers.

     (*) MTD blockdev handling and FTL.

     (*) JFFS - which uses set_bdev_super(), something it could avoid doing by
     	 taking a leaf out of JFFS2's book.

 (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and
     linux/elevator.h contingent on CONFIG_BLOCK being set.  sector_div() is,
     however, still used in places, and so is still available.

 (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and
     parts of linux/fs.h.

 (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.

 (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.

 (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK
     is not enabled.

 (*) fs/no-block.c is created to hold out-of-line stubs and things that are
     required when CONFIG_BLOCK is not set:

     (*) Default blockdev file operations (to give error ENODEV on opening).

 (*) Makes some /proc changes:

     (*) /proc/devices does not list any blockdevs.

     (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.

 (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.

 (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if
     given command other than Q_SYNC or if a special device is specified.

 (*) In init/do_mounts.c, no reference is made to the blockdev routines if
     CONFIG_BLOCK is not defined.  This does not prohibit NFS roots or JFFS2.

 (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return
     error ENOSYS by way of cond_syscall if so).

 (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if
     CONFIG_BLOCK is not set, since they can't then happen.

d1a8df9136 [POWERPC] fix up front-LED Kconfig
This patch fixes the front-LED Kconfig issues I introduced while
creating it. Apparently having a dependency isn't enough to have the
select not evaluated or something like that.

The patch also changes the default configuration for pmac32 select the
default for the LED to be the IDE trigger. While I was at it, I
completely updated the defconfig and also added snd-aoa to it.

It maintains backward compatibility with the old
BLK_DEV_IDE_PMAC_BLINK Kconfig option which now
simply selects the new code and influences the

3b6ce2497f [PATCH] ide Kconfig fixes
CONFIG_BLK_DEV_IDECS docu mentions everything and the kitchen sink, yet
fails to list the most important/widespread (IMHO) device: Compact Flash
PCMCIA adapters.

This incomplete description recently caused me to deselect the ide_cs
module, causing great pain soon thereafter when I realized why I had
actually enabled it some years ago.

Updates:
- make sure to mention Compact Flash adapters
- fix some random typos in ide Kconfig

There's no reason MAX_HWIFS needs to be ia64-specific, so set MAX_HWIFS

This reduces the default from 10 to 4, but I don't think that's a problem.
