powerpc/PCI: compute I/O space bus-to-resource offset consistently

2012-03-20T17:41:44+00:00

Make sure we compute CPU addresses (resource start/end) the same way both
when we set up the I/O aperture (hose->io_resource) and when we use
pcibios_bus_to_resource() to convert BAR values into resources.

This fixes a build failure ("cast from pointer to integer of different
size" in configs where resource_size_t is 64 bits but pointers are 32 bits)
I introduced in 6c5705fec63d.

powerpc/PCI: replace pci_probe_only with pci_flags

2012-02-24T03:18:58+00:00

We already use pci_flags, so this just sets pci_flags directly and removes
the intermediate step of figuring out pci_probe_only, then using it to set
pci_flags.

The PCI core provides a pci_flags definition (currently __weak), so drop
the powerpc definitions in favor of that.

powerpc/PCI: make pci_probe_only default to 0

2012-02-24T03:18:58+00:00

pci_probe_only is set on ppc64 to prevent resource re-allocation
by the core. It's meant to be used in very specific circumstances
such as when operating under a hypervisor that may prevent such
re-allocation.

Instead of default to 1, we make it default to 0 and explicitly
set it in the few cases where we need it.

This fixes FSL PCI which wants it clear among others.

powerpc/PCI: split PHB part out of pcibios_map_io_space()

2012-01-06T20:11:08+00:00

No functional change.  This is so we can use pcibios_phb_map_io_space()
before we have a struct pci_bus.

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.

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.
