powerpc/85xx: Handle PCIe initialization requires for P1021 class SoCs

2011-03-29T12:41:37+00:00

The P1011, P1012, P1015, P1016, P1020, P1021, P1024, & P1025 SoCs require
that we initialize the SERDES registers if the lanes are configured for
PCIe.  Additionally these devices PCIe controller do not support ASPM
and we have to explicitly disable it.

powerpc/fsl-pci: Determine pci_controller based on cfg addr for dts fixup

2011-01-14T07:32:19+00:00

Previously we passed in a specifically named struct pci_controller to
determine if we had setup the particular PCI bus.  Now we can search for
the struct so we dont have to depend on the name or the struct being
statically allocated.

Introduced new find_hose_by_cfg_addr() to get back a pci_controller struct
back by searching for it means we can do things like dynamically allocate
them or not have to expose the static structures to all users.

pci: Clean up PCI info when CONFIG_PCI_SCAN_SHOW

2010-11-14T22:46:46+00:00

This change does the following:
- Removes the printing of the PCI interrupt line value.  This is
  normally set to 0 by U-Boot on bootup and is rarely used during
  everyday operation.

- Prints out the PCI function number of a device.  Previously a device
  with multiple functions would be printed identically 2 times, which is
  generally confusing.  For example, on an Intel 2 port gigabit Ethernet
  card the following was displayed:
    ...
    04  01  8086  1010  0200  00
    04  01  8086  1010  0200  00
    ...

- Prints a text description of each device's PCI class instead of the
  raw PCI class code.  The textual description makes it much easier to
  determine what devices are installed on a PCI bus.

- Changes the general formatting of the PCI device output.

Previous output:

mpc83xx: Add support for MPC83xx PCI-E controllers

2009-01-22T00:43:49+00:00

This patch adds support for MPC83xx PCI-E controllers in Root Complex
mode.

The patch is based on Tony Li and Dave Liu work[1].

Though unlike the original patch, by default we don't register PCI-E
buses for use in U-Boot, we only configure the controllers for future
use in other OSes (Linux). This is done because we don't have enough
of spare BATs to map all the PCI-E regions.

To actually use PCI-E in U-Boot, users should explicitly define
CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And
only then U-Boot will able to access PCI-E, but at the cost of disabled
address translation.

pci: Allow for PCI addresses to be 64-bit

2008-10-24T22:32:49+00:00

PCI bus is inherently 64-bit.  While not all system require access to
the full 64-bit PCI address range some do.  This allows those systems
to enable the full PCI address width via CONFIG_SYS_PCI_64BIT.
