c2e49f706b mpc83xx: Add esd VME8349 board support
This patch adds support for the esd VME8349 board equipped with the
MPC8349. It's a VME PMC carrier board equipped with the Tundra
TSI148 VME-bridge.

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.

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.

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.

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.

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