it instead of defining IDE_ARCH_OBSOLETE_DEFAULTS in <arch/ide.h>.
v2:
* Define ide_default_irq() in ide-probe.c/ns87415.c if not already defined
and drop defining ide_default_irq() for CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=n.

* Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag for Motorola-Sandpoint platform
to sl82c105 host driver.
* Disable ide_generic host driver in arch/ppc/configs/sandpoint_defconfig
and enable sl82c105 one.
* Remove ppc_ide_md hooks from arch/ppc/platforms/sandpoint.c - no need for
them (sl82c105 host driver takes care of all this setup).
* Then remove no longer needed <linux/ide.h> include.
* Also update arch/ppc/platforms/sandpoint.h.
Unfortunately (unlike lopec's case) sl82c105 host driver was not enabled
in defconfing so there is a funcionality change.
[ Not a big deal since sl82c105 is superior over ide_generic. ]

* Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag for Motorola-LoPEC platform
to sl82c105 host driver.
* Remove ppc_ide_md hooks from arch/ppc/platforms/lopec.c - no need for
them (sl82c105 host driver takes care of all this setup).
* Then remove no longer needed <linux/ide.h> include.
Looking at arch/ppc/configs/lopec_defconfig:
...
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_IDEPCI=y
# CONFIG_IDEPCI_SHARE_IRQ is not set
# CONFIG_BLK_DEV_OFFBOARD is not set
CONFIG_BLK_DEV_GENERIC=y
# CONFIG_BLK_DEV_OPTI621 is not set
CONFIG_BLK_DEV_SL82C105=y
...
there should be no functional changes unless somebody preferred to disable
sl82c105 host driver and use only ide_generic one (but why would anybody
want to do such thing :-).
PS It seems that lopec_defconfig hasn't been updated for ages but if somebody
is going to do it please look into disabling IDE_GENERIC and BLK_DEV_GENERIC
config options. Thanks.

* Initialize IDE ports in mpc8xx_ide_probe().
* Remove m8xx_ide_init() and ppc_ide_md hooks - no need for them
(IDE mpc8xx host driver takes care of all this setup).
* Remove needless 'if (irq)' and 'if (data_port >= MAX_HWIFS)' checks
from m8xx_ide_init_hwif_ports().
* Remove 'ctrl_port' and 'irq' arguments from m8xx_ide_init_hwif_ports().
* Rename m8xx_ide_init_hwif_ports() to m8xx_ide_init_ports().
* Add __init tag to m8xx_ide_init_ports().
This patch fixes hwif->irq always being overriden to 0 (== auto-probe, is
this even working on PPC?) because of ide_init_default_irq() call in ide.c.
There should be no other functional changes.

Removing the atomic tests for pc's is unobjectionable. Since this driver will
probably go to /dev/null soon, the atomic tests for tape->flags are left in
place for there are some situations where they're needed (chrdev DSC handling,
low level pipeline operation and so on). While at it, rename all test/set flag
bit defines explicitly to *_FLAG_* for clarity.

scc_pata has the different BAR configuration and using ide_setup_pci_device()
is inappropriate.
(ide_setup_pci_device() expects a normal PCI IDE controller with
BAR0..BAR3 either non-existant or being primary/secondary port bases
in I/O space.)
This patch do all needed setup itself instead of calling ide_setup_pci_device().
