Revert "[POWERPC] Don't get PCI IRQ from OF for devices with no IRQ"

2006-10-08T22:38:22+00:00

This reverts commit 41550c5128150175197257b6ceab2cd50dea7b51.

Quoth Ben Herrenschmidt:
 "Please revert this one for now.  It seems to break G5s :( Looks like
  PCI cells inside Apple IO ASICs don't have a PCI_INTERRUPT_LINE set.
  I need to figure out a better fix."

[POWERPC] Don't get PCI IRQ from OF for devices with no IRQ

2006-10-06T11:10:41+00:00

This patch adds checking of the PCI_INTERRUPT_PIN register before
using standard OF parsing to retreive PCI interrupts. The reason is
that some PCI devices may have no PCI interrupt, though they may have
interrupts attached via other means. In this case, we shall not use
irq->pdev, but device-specific code can later retreive those interrupts
instead.

Without that patch, Maple and derivatives don't get the right interrupt
for the second IDE channel as the linux IDE code fallsback to the PCI
irq instead of trying to use the legacy ones for the on-board controller
(which has no PCI_INTERRUPT_PIN). Having no PCI IRQ assign to it (as it
doesn't request any) fixes it.

[POWERPC] Make OF irq map code detect more error cases

2006-08-30T04:31:03+00:00

Device-tree bugs on js20 with some versions of SLOF were causing the
interrupt for IDE to not be parsed correctly and fail to boot. This
patch adds a bit more sanity checking to the parser to detect some of
those errors and fail instead of returning bogus information.  The
powerpc PCI code can then trigger a fallback that works on those
machines.

[POWERPC] Constify & voidify get_property()

2006-07-31T05:55:04+00:00

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

[PATCH] powerpc: make OF interrupt tree parsing more strict

2006-07-10T20:24:20+00:00

This patch fixes a bit of boundchecking in the new Open Firmware interrupt
tree parsing code.  It's important that it fails when things aren't correct in
order to trigger fallback mecanisms that are necessary to make some machines
work properly.

[POWERPC] Use const qualifiers for prom parsing utilites

2006-07-07T10:19:16+00:00

The of_bus callbacks map and get_flags can be constified, as they don't
alter the range or addr arguments. of_dump_addr and of_read_addr can
also be constified.
