pci: Add functions to read and write a BAR address

2014-11-25T13:34:00+00:00

Some PCI functions cannot be auto-configured. Add a function to set up a
fixed BAR which can be used in these situations. Also add a function to read
the current address of a BAR.

pci: Honour pci_skip_dev()

2014-11-23T11:49:01+00:00

When enumerating devices, honour the pci_skip_dev() function. This can
be used by PCI controller drivers to restrict which devices will be
probed.

This is required by the NVIDIA Tegra PCIe controller driver, which will
fail with a data abort exception if an access is attempted to a device
number larger than 0 outside of bus 0. pci_skip_dev() is therefore
implemented to prevent any such accesses.

pci: add support for board_pci_fixup_dev function

2014-09-09T14:15:02+00:00

Some board-level drivers may wish to have per-device fixup functions
for PCI devices.

pci.h: allow inclusion in assembly source

2013-11-09T16:21:01+00:00

This patch simply #ifdef's out the C-specific parts of pci.h when it is
included by an assembly file. This will allow the macros it contains to
be used from assembly source as will be done in a followup commit adding
support for more modern MIPS Malta boards.

PCIe:change the method to get the address of a requested capability in configuration space.

2013-10-16T23:15:17+00:00

Previously, the address of a requested capability is define like that
	"#define PCI_DCR	0x78"
But, the addresses of capabilities is different with regard to PCIe revs.
So this method is not flexible.

Now a function to get the address of a requested capability is added and used.
It can get the address dynamically by capability ID.
The step of this function:
	1. Read Status register in PCIe configuration space to confirm that
	   Capabilities List is valid.
	2. Find the address of Capabilities Pointer Register.
	3. Find the address of requested capability from the first capability.

powerpc/pcie: add PCIe version 3.x support

2013-08-09T19:41:41+00:00

T4240 PCIe IP is version 3.0 and has some update comparing previous
QorIQ products.

1.  Move Freescale specific register define
to
arch/powerpc/include/asm/fsl_pci.h
and update the register offset define for T4240.

2. add the status/control register define
use status/control register to judge the link status

3. The original code uses 'Programming Interface' field to judge if PCIE is
EP or RC mode, however, T4240 does not support this functionality.
According to PCIE specification, 'Header Type' offset 0x0e is used to
indicate header type, so for PCIE controller, the patch changes code to
use 'Header Type' field to identify if the PCIE is RC or EP mode.

This patch fixes  the PCIe card link up issue on T4240QDS.

pci: Convert extern inline functions to static inline

2013-06-26T14:16:40+00:00

I am not sure of the meaning of extern inline, but this gives errors
when building with function instrumenting enabled. Change these functions
to static inline.

pci: introduce CONFIG_PCI_INDIRECT_BRIDGE option

2013-06-07T18:17:01+00:00

The pci_indirect.c file is always compiled when
CONFIG_PCI is defined although the indirect PCI
bridge support is not needed by every board.

Introduce a new CONFIG_PCI_INDIRECT_BRIDGE
config option and only compile indirect PCI
bridge support if this options is enabled.

Also add the new option into the configuration
files of the boards which needs that.

Compile tested for powerpc, x86, arm and nds32.
MAKEALL results:
