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.

2d43e873a2 pci: give preference to non-PCI_REGION_SYS_MEMORY regions when matching
When we search for an address match in pci_hose_{phys_to_bus,bus_to_phys}
we should give preference to memory regions that aren't system memory.

Its possible that we have over mapped system memory in the regions and
we want to avoid depending on the order of the regions.

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.

dc1da42f81 pci: Move PCI device configuration check into a separate weak function
This patch moves the check, if a device should be skipped in PCI PNP
configuration into the function pci_skip_dev(). This function is defined
as weak so that it can be overwritten by a platform specific one if
needed. The check if the device should get printed in the PCI summary upon
bootup (when CONFIG_PCI_SCAN_SHOW is defined) is moved to the function
pci_print_dev() which is also defined as weak too.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

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.

55774b512f pci: Add CONFIG_PCI_SKIP_HOST_BRIDGE config option
In current source code, when the device number of PCI is 0, process PCI
bridge without fail. However, when the device number is 0, it is not PCI
always bridge. There are times when device of PCI allocates.

When CONFIG_PCI_SKIP_HOST_BRIDGE is enable, this problem is solved when
use this patch.
