    Yes, in order to narrow things down: please boot 4.11 without PCI
    support in U-Boot.

    The problem is that mx6q does not have a way to properly reset the PCI block.

    On the board I tested there is no PCI support in U-Boot.

    Maybe we need the following approach in U-Boot as Lucas did for Barebox:

    According to this patch that went into 4.11 the bootloader must put
    PCI back in a safe state:
