The header files for the Pb1200/DBAu1200 boards have wrong definition for the
IDE interface's decoded range length -- it should be 512 bytes according to
what the IDE driver does. In addition, the IDE platform device claims 1 byte
too many for its memory resource -- fix the platform code and the IDE driver

Fix kernel oops due to machine check occuring in init_chipset_siimage() on PPC
44x platforms. These 32-bit CPUs have 36-bit physical address and PCI I/O and
memory spaces are mapped beyond 4 GB; arch/ppc/ code has a fixup in ioremap()
that creates an illusion of the PCI I/O and memory resources being mapped below
4 GB, while arch/powerpc/ code got rid of this fixup with PPC 44x having instead
CONFIG_RESOURCES_64BIT=y -- this causes the resources to be truncated to 32-bit
'unsigned long' type in this driver, and so non-existant memory being ioremap'ed
and then accessed...

This reverts commit b140b99c41.
[ conflict in drivers/ide/ide-probe.c fixed manually ]
It turned out that probing order change causes problems for some drives:
http://bugzilla.kernel.org/show_bug.cgi?id=10239
Since root causes are still being investigated and are unlikely to be fixed
before 2.6.25 lets revert this change for now. As a result cable detection
becomes less reliable when compared with 2.6.24 but the affected drives are
useable again.

Now that we handle all the special commands using REQ_TYPE_ATA_TASKFILE
rather than using the old REQ_TYPE_ATA_CMD model, we need to also
emulate the lack of full taskfile data that comes with the old command
model (ie when commands are generated with the HDIO_DRIVE_CMD ioctl
rather than using the HDIO_DRIVE_TASK[FILE] ioctls).
In particular, this means that we should handle command completion the
more relaxed way that the old drive_cmd_intr() code did. It allows
commands to finish early even if they don't use up all the data that we
thought we had for them.
This fixes a regression seen by Anders Eriksson where some SMART
commands sent by smartd would cause a boot-time system hang on his
machine because the IDE command handling code didn't realize that the
command had completed.
