Hi,
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?
Thanks,
Prathamesh
