2008-07-21driver core: fix a lot of printk usages of bus_idGreg Kroah-Hartman
We have the dev_printk() variants for this kind of thing, use them instead of directly trying to access the bus_id field of struct device. This is done in order to remove bus_id entirely. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-05-14[POWERPC] Move xmon_irq() declaration into xmon.hMichael Ellerman

2008-01-25[POWERPC] Revert chrp_pci_fixup_vt8231_ata devinit to fix libata on pegasosOlaf Hering
Commit 6d98bda79bea0e1be26c0767d0e9923ad3b72f2e changed the init order for chrp_pci_fixup_vt8231_ata(). It can not work anymore because either the irq is not yet set to 14 or pci_get_device() returns nothing. At least the printk() in chrp_pci_fixup_vt8231_ata() does not trigger anymore. pata_via works again on Pegasos with the change below.

2007-12-20[POWERPC] pci32: Add flags modifying the PCI code behaviourBenjamin Herrenschmidt
This adds to the 32 bits PCI code some flags, replacing the old pci_assign_all_busses global, that allow us to control various aspects of the PCI probing, such as whether to re-assign all resources or not, or to not try to assign anything at all. This also adds the flag x86 already has to avoid ISA alignment on bridges that don't have ISA forwarding enabled (no legacy devices on the top level bus) and sets it for PowerMacs.

2007-12-10powerpc: Fix IDE legacy vs. native fixupsBenjamin Herrenschmidt
PowerMac and CHRP/BriQ platforms have quirks to switch some IDE controllers from legacy mode to fully native mode. Those quirks however will not work properly anymore due to a change to the generic code to better handle legacy IDE resources. This fixes it by moving those quirk to "early" quirks (so they run before resources are probed for the devices) and clearing all BARs after the conversion to force a reallocation of sane values.

The following includes were removed: <asm/amigappc.h> <asm/bootinfo.h> <asm/ppcboot.h> <asm/ppc_sys.h> <asm/residual.h> <asm/m8260_pci.h> This also caused platforms/embedded6xx/mpc7448_hpc2.h to no longer be needed and thus removed.

2007-08-22[POWERPC] Advertise correct IDE mode on Pegasos2Olaf Hering
The built-in IDE controller is configured in legacy mode, but the PCI registers advertise native mode. Force the PCI class into legacy mode. This allows pata_via to access two drives. The Pegasos specific irq enforcement in the via82cxxx driver must stay because there is apparently no generic way to setup irq per channel.

2007-03-06mv643xx_eth: Place explicit port number in mv643xx_eth_platform_dataDale Farnsworth
We were using the platform_device.id field to identify which ethernet port is used for mv643xx_eth device. This is not generally correct. It will be incorrect, for example, if a hardware platform uses a single port but not the first port. Here, we add an explicit port_number field to struct mv643xx_eth_platform_data. This makes the mv643xx_eth_platform_data structure required, but that isn't an issue since all users currently provide it already.

2006-12-04[POWERPC] Make pci_read_irq_line the defaultBenjamin Herrenschmidt
This patch reworks the way IRQs are fixed up on PCI for arch powerpc. It makes pci_read_irq_line() called by default in the PCI code for devices that are probed, and add an optional per-device fixup in ppc_md for platforms that really need to correct what they obtain from pci_read_irq_line(). It also removes ppc_md.irq_bus_setup which was only used by pSeries and should not be needed anymore. I've also removed the pSeries s7a workaround as it can't work with the current interrupt code anyway. I'm trying to get one of these machines working so I can test a proper fix for that problem. I also haven't updated the old-style fixup code from 85xx_cds.c because it's actually buggy :) It assigns pci_dev->irq hard coded numbers which is no good with the new IRQ mapping code. It should at least use irq_create_mapping(NULL, hard_coded_number); and possibly also set_irq_type() to set them as level low.

2006-10-25[POWERPC] Fix CHRP platforms with only 8259Benjamin Herrenschmidt
On CHRP platforms with only a 8259 controller, we should set the default IRQ host to the 8259 driver's one for the IRQ probing fallbacks to work in case the IRQ tree is incorrect (like on Pegasos for example).

Pseudo-CHRP machines like Pegasos without an MPIC would crash at boot if CONFIG_SMP was set because the "smp_ops" pointer was set to MPIC related ops unconditionally.

include/linux/version.h contained both actual KERNEL version and UTS_RELEASE that contains a subset from git SHA1 for when kernel was compiled as part of a git repository.

2006-07-03[POWERPC] Add new interrupt mapping core and change platforms to use itBenjamin Herrenschmidt
This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.
