The driver looks suspiciously like the one that Hauke already submitted a
while ago for bcm53xx. Please come up with a merged driver that works for
both.

Are you sure that iProc isn't based on the BCMA bus infrastructure after
all? Even the physical address of your PCI host falls into the address
range that is used for the internal BCMA bus on the other chips!
