4c253fdb2a 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

35db1c6d34 drivers/fsl_pci_init: Fix inbound window mapping bug
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.

cd42516242 powerpc: fix pci window initialization to work with > 4GB DRAM
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.

612ea01018 pci/fsl_pci_init: Enable larger address and setting inbound windows properly
* 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

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.

589c04271d Convert mpc7448hpc2 to CONFIG_OF_LIBFDT
This was configured to use the deprecated CONFIG_OF_FLAT_TREE, change
to CONFIG_OF_LIBFDT.

WARNING: This conversion is untested because I do not have a board to
test it on.

NOTE: The FDT blob (DTS) must have an /aliases/ethernet0 and (optionally)
/aliases/ethernet1 property for the ethernet to work.

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.

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
