I have indeed disabled earlyprintk. Initially by removing it from the command line, and then even by disabling CONFIG_DEBUG_LL. In fact the original bug report I had came from my colleague Gregory Clement, who precisely reported to me that a PCIe card was properly detected on his Armada 385 board when earlyprintk was enabled, but the PCIe card was not detected when earlyprintk was disabled. At the time, I was able to reproduce the problem as well on my Armada 385, and debugged it to find that the mvebu_pcie_set_local_dev_nr().
