[QUESTION] 440EPx with PCI to PCIe bridge error

["Steven A. Falco" <sfalco@harris.com>]

I have a Sequoia board (440EPx) with kernel 2.6.27.9.  I've recently
plugged in a PLX adapter board to convert one of the PCI connectors
on the Sequoia to PCIe.

When the kernel boots, I get the following error messages regarding
mem resource allocation.  Device 0000:00:0c.0 is the PCI<->PCIe bridge,
and device 0000:01:00.0 is an FPGA PCIe evaluation board.

	PCI host bridge /plb/pci@1ec000000 (primary) ranges:
	 MEM 0x0000000180000000..0x000000018fffffff -> 0x0000000080000000
	  IO 0x00000001e8000000..0x00000001e80fffff -> 0x0000000000000000

	pci 0000:00:0c.0:   MEM window: disabled
	pci 0000:00:0c.0:   PREFETCH window: disabled

Plain PCI cards plugged directly into the Sequoia work fine.  Is there
something I have to add to the .dts file to represent the PCI<->PCIe
bridge?

	Thanks,
