PCI: Remove unused pci_dma_burst_advice()

2015-06-08T12:56:43+00:00

pci_dma_burst_advice() was added by e24c2d963a60 ("[PATCH] PCI: DMA
bursting advice") but apparently never used.  Remove it.

We don't have any arch specific scatterlist now that parisc switched over
to the generic one.

MIPS: PCI: Add a hook for IORESOURCE_BUS in pci_controller/bridge_controller

2015-04-01T15:22:16+00:00

On SGI Origin 2k/Onyx2 and SGI Octane systems, there can exist multiple PCI
buses attached to the Xtalk bus.  The current code will stop counting PCI buses
after it finds the first one.  If one installs the optional PCI cardcage
("shoebox") into these systems, because of the order of the Xtalk widgets, the
current PCI code will find the cardcage first, and fail to detect the BaseIO
PCI devices, which are on a higher Xtalk widget ID.

This patch adds the hooks needed for resolving this issue in the IP27 PCI code
(in a later patch).

Verified on both an SGI Onyx2 and an SGI Octane.

mips: pci: Add ifdef around pci_proc_domain

2015-02-20T12:16:14+00:00

Without these, there are multiple definitions of pci_proc_domain()
and pci_domain_nr() if linux/pci.h and asm/pci.h are included.

Add #ifdefs around them

PCI: Turn pcibios_penalize_isa_irq() into a weak function

2014-05-27T22:23:58+00:00

pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA
is not used by some architectures.  Make pcibios_penalize_isa_irq() a
__weak function to simplify the code.  This removes the need for new
platforms to add stub implementations of pcibios_penalize_isa_irq().

PCI: use weak functions for MSI arch-specific functions

2013-08-12T15:26:39+00:00

Until now, the MSI architecture-specific functions could be overloaded
using a fairly complex set of #define and compile-time
conditionals. In order to prepare for the introduction of the msi_chip
infrastructure, it is desirable to switch all those functions to use
the 'weak' mechanism. This commit converts all the architectures that
were overidding those MSI functions to use the new strategy.

Note that we keep two separate, non-weak, functions
default_teardown_msi_irqs() and default_restore_msi_irqs() for the
default behavior of the arch_teardown_msi_irqs() and
arch_restore_msi_irqs(), as the default behavior is needed by x86 PCI
code.

MIPS: remove alloc_pci_controller prototype

2013-07-01T13:10:52+00:00

Commit 610019baddcb4c4c323c12cd44ca7f73d7145d6f ("[MIPS] Remove unused
function alloc_pci_controller.") removed the function, but left the
prototype in the header file.

Remove it as well so people don't get tempted to use it and wonder why
it doesn't work.
