pci/fsl_pci_init: Enable inbound PCI config cycles

2008-12-20T00:10:45+00:00

Add fsl_pci_config_unlock() function to enable a
PCI/PCIe interface configured in agent/endpoint mode to
respond to inbound PCI configuration cycles.

drivers/fsl_pci_init: Fix compile warning

fsl_pci_init.c: In function 'fsl_pci_setup_inbound_windows':
fsl_pci_init.c:122: warning: comparison is always true due to limited range of data type

The check only makes sense if we are CONFIG_PHYS_64BIT

drivers/fsl_pci_init: Fix inbound window mapping bug

2008-12-04T04:48:50+00:00

The current code will cause the creation of a 4GB window
starting at 0 if we have more than 4GB of RAM installed,
which overlaps with PCI_MEM space and causes pci_bus_to_phys()
to return erroneous information. Limit the size to 4GB - 1;
which causes the code to create one 2GB and one 1GB window
instead.

powerpc: fix pci window initialization to work with > 4GB DRAM

2008-10-27T21:27:58+00:00

The existing code has a few errors that need to be fixed in
order to support large RAM sizes.  Fix those, and add a
comment to make it clearer.

pci/fsl_pci_init: Add a common PCI inbound setup function

2008-10-24T22:35:05+00:00

Add a common setup function that determines the pci_region(s) based
on how much memory we have in the system.

pci/fsl_pci_init: Enable larger address and setting inbound windows properly

2008-10-24T22:35:02+00:00

* PCI Inbound window was setup incorrectly.  The PCI address and system
  address were swapped.  The PCI address should be setting piwar/piwbear
  and the system address should be setting pitar.

* Removed masking of addresses to allow for system address to support
  system address & PCI address >32-bits

* Set PIWBEAR & POTEAR to allow for full 64-bit PCI addresses

* Respect the PCI_REGION_PREFETCH for inbound windows

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.
