How to enable PCIe in Yocto project on board i.MX6QP-SABRESD?

I am using Yocto to build Linux image to run on i.mx6qp-sabresd board.


I set DISTRO = 'fsl-imx-fb' and built two types images: core-image-base and fsl-image-machine-test.


I booted the board with the images copied on SD card, and from log I found both of them not bringing up the PCIe controller.


The build procedure I am following the doc 'i.MX_Yocto_Project_User's_Guide.pdf', and I didn't apply any changes on the Yocto project.


Please help to inform:

1. If this release Yocto project support PCIe for this board?

2. If yes, how to enable the PCIe in Linux?


The Yocto version is 'NXP's 4.1.15-2.1.0 Yocto Project BSP', and I also attach the logs for your check.


Thank you very much.
