How do you make the Linux kernel inherit bios 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, i.e. I want Linux to only read/probe the config registers. 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?
