cc2a8c7751 PCI: Add pci_last_busno() helper
This is just a handy routine that reports last PCI busno: we walk
down all the hoses and return last hose's last_busno.

Will be used by PCI/PCIe initialization code.

6e61fae4d3 drivers/pci: Create pci_map_bar function
It is no longer always true that the pci bus address can be
used as the virtual address for pci accesses.  pci_map_bar()
is created to return the virtual address for a pci region.

ff4e66e93c pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarity
The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.

Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

fd6646c0b9 mpc83xx: Add support for MPC83xx PCI-E controllers
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.

30e76d5e3b pci: Allow for PCI addresses to be 64-bit
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.

36f32675f4 Update pci code to use phys_addr_t
Physical addrs need to be represented by phys_addr_t, not
unsigned long.  Otherwise, systems that use CONFIG_PHYS_64BIT
are going to fail mightily.

63cec5814f Make MPC8641's PCI/PCI-E driver a common driver for many FSL parts.
All of the PCI/PCI-Express driver and initialization code that
was in the MPC8641HPCN port has now been moved into the common
drivers/fsl_pci_init.c.  In a subsequent patch, this will be
utilized by the 85xx ports as well.

Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added.

Also enable the second PCI-Express controller on 8641
by getting its BATS and CFG_ setup right.

Fixed a u16 vendor compiler warning in AHCI driver too.

a179012e37 Added support for PCI prefetchable region and BARs
If a host controller sets up a region as prefetchable and
a device's BAR denotes it as prefetchable, allocate the
BAR into the prefetch region.

If a BAR is prefetchable and no prefetchable region has
been setup by the controller we fall back to allocating
the BAR into the normally memory region.

* Patch by Jon Diekema, 12 Nov 2002:
  - Adding URL for IEEE OUI lookup
  - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
    being defined.
  - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
    root-on-nfs macros are designed to switch how the default boot
    method gets defined.
