Why are you setting those? Does the driver load ok if you do not
specify those driver options?

Potentially the driver parameters combination is causing a problem, or
your ARM SoC may not be PCIe compliant. A lot of small SoC's just
throw a PCIe bridge on the SoC without proper coherency in place
between the CPU and the PCIe bus. PCIe requires cohorency with the
CPU (i.e., the device can snoop the CPU's cache).
