Hello, I am working on yocto KL4.1.15 for imx6qsabreauto board, I can't enable pcie host/bus driver in BSP.

I added pcie into dts file and confirm it included into .dtb file. I modified defconfig file to add CONFIG_PCI=y and relative CONFIG_PCI*.

After I bring up the os, tab lspci, the warning message show as below:

Can not open /proc/bus/pci.

it seems that PCI interface is not enabled, CONFIG_PCI is not work..

the Branch is git:// -b imx-4.1.15-1.0.0_ga.

build cmd is:

EULA=1 MACHINE=imx6qsabreauto source -b build -e x11

bitbake core-image-base
