The alim15x3.c havn't been update for 3 years. Recently when we use this
"ULI M1573" south bridge chip found that can't mount CDROM(VCD) smoothly,
must waiting for a long time. After I check the "ULI M1573" south bridge
datasheet, I found the reason. The reason is the "ULI M1573" version in
the Linux is "0xC7" not "0xC4" anymore So I was modified the source than it
was successed.

Instead of the two status values struct pcmcia_device->p_state and state,
use descriptive bitfields. Most value-checking in drivers was invalid, as
the core now only calls the ->remove() (a.k.a. detach) function in case the
attachement _and_ configuration was successful.

Most of the driver initialization isn't done in the .probe function, but in
the internal _config() functions. Make them return a value, so that .probe
can properly report whether the probing of the device succeeded or not.

pcmcia_disable_device(struct pcmcia_device *p_dev) performs the necessary
cleanups upon device or driver removal: it calls the appropriate
pcmcia_release_* functions, and can replace (most) of the current drivers'

Some quick backport bits from the libata PATA work to fix things found in
the sis driver. The piix driver needs some fixes too but those are way to
large and need someone working on old IDE with time to do them.
This patch fixes the case where random bits get loaded into SIS timing
registers according to the description of the correct behaviour from
Vojtech Pavlik. It also adds the SiS5517 ATA16 chipset which is not
currently supported by the driver. Thanks to Conrad Harriss for loaning me
the machine with the 5517 chipset.

This removes statically assigned platform numbers and reworks the
powerpc platform probe code to use a better mechanism. With this,
board support files can simply declare a new machine type with a
macro, and implement a probe() function that uses the flattened
device-tree to detect if they apply for a given machine.
We now have a machine_is() macro that replaces the comparisons of
_machine with the various PLATFORM_* constants. This commit also
changes various drivers to use the new macro instead of looking at
_machine.

I just purchased a HighPoint Rocket 1520 SATA controller. There seems to
be no libata driver (yet), but there is an ide driver, hpt366. When the
driver gets loaded, it causes a kernel NULL pointer dereference in
pci_bus_clock_list. It seems to be because the driver is waiting for clock
stabilization in init_hpt37x() which never comes. The driver just
continues on with the pci drvdata set to NULL, instead of a valid clock
entry. The following patch prevents the NULL dereference from happening,
but instead exit with an error.

This patch stops CompactFlash devices being marked as removable. They are
not removable (as defined by Linux) as the media and device are
inseparable. When a card is removed, the whole device is removed from the
system and never sits in a media-less state.
This stops some nasty udev device creation/destruction loops.
Further, once this change is made, there is no need for ide to can be
removed from ide_drive_t.

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
