Inherit U-boot's pcie config

I have U-boot setting up my pcie config the way i like. I was wondering if there was some way to make linux inherit the bootloader/bios pcie config. Currently when Linux boots it wipes out all the configuration that is done in U-boot. I have tried using the kernel command pci=bios, but that doesn't seem work. Is there any other kernel command line argument or kernel configuration that I can use to do this?

I have tried pci=firmware as well, but kernel says " PCI: Unknown option `firmware' ". I have also tried setting the PPC_PCI_PROBE_ONLY flag on ppc_pci_flags with no luck.
