powerpc: add export.h to files making use of EXPORT_SYMBOL

2011-10-31T23:30:37+00:00

With module.h being implicitly everywhere via device.h, the absence
of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the
device.h file, we need to explicitly include these files now.

powerpc: rename ppc_pci__flags to pci__flags

2011-07-12T14:28:04+00:00

This renames pci flags functions and enums in preparation for creating
generic version in asm-generic/pci-bridge.h. The following search and
replace is done:

s/ppc_pci_/pci_/
s/PPC_PCI_/PCI_/

Direct accesses to ppc_pci_flag variable are replaced with helper
functions.

powerpc/pci: Make both ppc32 and ppc64 use sysdata for pci_controller

2011-02-04T18:46:51+00:00

Currently, ppc32 uses sysdata for the pci_controller pointer, and
ppc64 uses it to hold the device_node pointer.  This patch moves the
of_node pointer into (struct pci_bus*)->dev.of_node and
(struct pci_dev*)->dev.of_node so that sysdata can be converted to always
use the pci_controller pointer instead.  It also fixes up the
allocating of pci devices so that the of_node pointer gets assigned
consistently and increments the ref count.

powerpc/pci: Use printf extension %pR for struct resource

Using %pR standardizes the struct resource output.

of: add 'of_' prefix to machine_is_compatible()

2010-02-09T15:33:00+00:00

machine is compatible is an OF-specific call.  It should have
the of_ prefix to protect the global namespace.

powerpc/pci: Merge ppc32 and ppc64 versions of phb_scan()

2009-09-02T05:45:53+00:00

The two versions are doing almost exactly the same thing.  No need to
maintain them as separate files.  This patch also has the side effect
of making the PCI device tree scanning code available to 32 bit powerpc
machines, but no board ports actually make use of this feature at this
point.

powerpc/pci: move pci_64.c device tree scanning code into pci-common.c

2009-08-28T04:24:15+00:00

The PCI device tree scanning code in pci_64.c is some useful functionality.
It allows PCI devices to be described in the device tree instead of being
probed for, which in turn allows pci devices to use all of the device tree
facilities to describe complex PCI bus architectures like GPIO and IRQ
routing (perhaps not a common situation for desktop or server systems,
but useful for embedded systems with on-board PCI devices).

This patch moves the device tree scanning into pci-common.c so it is
available for 32-bit powerpc machines too.

powerpc: Fix warning when printing a resource_size_t

2009-06-09T06:47:41+00:00

resource_size_t is 64 bits on PowerPC 64.

powerpc: Shield code specific to 64-bit server processors

2009-06-09T06:47:38+00:00

This is a random collection of added ifdef's around portions of
code that only mak sense on server processors. Using either
CONFIG_PPC_STD_MMU_64 or CONFIG_PPC_BOOK3S as seems appropriate.

This is meant to make the future merging of Book3E 64-bit support
easier.
