PCI: Unify pci_resource_to_user() declarations

2016-06-17T19:43:34+00:00

Replace the pci_resource_to_user() declarations in each arch that defines
HAVE_ARCH_PCI_RESOURCE_TO_USER with a single one in linux/pci.h.

Change the MIPS static inline implementation to a non-inline version so the
static inline doesn't conflict with the new non-static linux/pci.h
declaration.

No functional change intended.

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.

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().

sparc: drop use of extern for prototypes in arch/sparc/include/asm

2014-05-19T02:01:29+00:00

Drop extern for all prototypes and adjust alignment of parameters
as required after the removal.
In a few rare cases adjust linelength to conform to maximum 80 chars,
and likewise in a few rare cases adjust alignment of parameters
to static functions.

PCI: collapse pcibios_resource_to_bus

2012-02-24T03:19:04+00:00

Everybody uses the generic pcibios_resource_to_bus() supplied by the core
now, so remove the ARCH_HAS_GENERIC_PCI_OFFSETS used during conversion.

sparc/PCI: get rid of device resource fixups

2012-02-24T03:19:04+00:00

Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

N.B. Leon apparently never uses initial BAR values, so it didn't matter
that we never fixed up the I/O resources from bus address to CPU addresses.

Other sparc uses pci_of_scan_bus(), which sets device resources directly
to CPU addresses, not bus addresses, so it didn't need pcibios_fixup_bus()
either.  But by telling the core about the offsets, we can nuke
pcibios_resource_to_bus().

PCI: SPARC: convert pcibios_set_master() to a non-inlined function

2012-01-06T20:10:39+00:00

This patch converts SPARC's architecture-specific
'pcibios_set_master()' routine to a non-inlined function.  This will
allow follow on patches to create a generic 'pcibios_set_master()'
function using the '__weak' attribute which can be used by all
architectures as a default which, if necessary, can then be over-
ridden by architecture-specific code.

Converting 'pci_bios_set_master()' to a non-inlined function will
allow SPARC's 'pcibios_set_master()' implementation to remain
architecture-specific after the generic version is introduced and
thus, not change current behavior.

No functional change.

pci/of: Consolidate pci_device_to_OF_node()

2011-06-07T23:08:43+00:00

All archs do more or less the same thing now, move it into
a single generic place.

I chose pci.h rather than of_pci.h to avoid having to change
all call-sites to include the later.

sparc: remove dma64_addr_t usage

2010-10-28T01:03:17+00:00

dma64_addr_t looks pointless (at least there is no point that an
architecture has the own dma64_addr_t typedef).

dma_addr_t is set to 32 or 64 bits appropriately. You can use u64
at places where you know that 64 bit address is always necessary.

Let's use u64 instead for sparc32.

Looks like PCI654_REQUIRED_MASK or PCI64_ADR_BASE isn't used. They can
be removed?
