U-boot Hang on IMX6QP with PCIe support enabled

I am having custom board with imx6qp. I have enabled PCIe support in u-boot( version 2015.04).

I observed that u-boot hangs at  imx_pcie_regions_setup in drivers/pci/pcie_imx.c. The same uboot is able to work on sabresd board(Though it says pcie phy link never came up), without hang. 

I observe the similar behavior  with the kernel (3.14.52) too.

What is the solution for this issue? Is there any patch available for uboot to work with imx6qp?
