pci: pcie_imx: Fix hang on mx6qp

2015-10-15T13:05:13+00:00

PCI driver currently hangs on mx6qp.

Toggle the reset bit with the appropriate timings to fix the issue.

Based on the FSL kernel driver implementation.

pci: Fix expansion ROM programming for multi-function devices

2015-10-08T18:09:09+00:00

PCI_HEADER_TYPE register (offset 0x0e) bit 7 is an indicator
for multi-function devices. We should mask it off before using
it as the header type.

dm: pci: Add an inline API to test if a device is on a PCI bus

2015-09-17T01:53:52+00:00

Introduce device_is_on_pci_bus() which can be utilized by driver
to test if a device is on a PCI bus.

dm: pci: Allow a PCI bus to be found without an alias

2015-09-09T13:48:03+00:00

At present, until a PCI bus is probed, it cannot be found by its sequence
number unless it has an alias. This is the same with any device.

However with PCI this is more annoying than usual, since bus 0 is always the
same device.

Add a function that tries a little harder to locate PCI bus 0. This means
that PCI enumeration will happen automatically on the first access.

pci/layerscape: Setup mmu-masters property for the PCIe

2015-09-02T02:49:27+00:00

Setup mmu-masters property for the PCIe controllers. This would be
used by the Linux SMMU driver, while setting up stream ID table mappings
for the PCIe devices.

In pci_uclass_child_post_bind(), bdf is extracted from fdt_pci_addr.
Mask bus number before save it to pplat->devfn.

x86: fsp: Call fsp_init_phase_pci() in pci_uclass_post_probe()

2015-08-26T14:54:12+00:00

Per Intel FSP specification, we should call FSP notify API to
inform FSP that PCI enumeration has been done so that FSP will
do any necessary initialization as required by the chipset's
BIOS Writer's Guide (BWG).

Unfortunately we have to put this call here as with driver model,
the enumeration is all done on a lazy basis as needed, so until
something is touched on PCI it won't happen.

Note we only call this after U-Boot is relocated and root bus has
finished probing.

dm: pci: Support selected device/driver binding before relocation

2015-08-26T14:54:11+00:00

On some platforms pci devices behind bridge need to be probed (eg:
a pci uart on recent x86 chipset) before relocation. But we won't
bind all devices found during the enumeration. Only devices whose
driver with DM_FLAG_PRE_RELOC set will be bound. Any other generic
devices except bridges won't be bound.
