Hi all, I've noticed the following: In function pci_process_bridge_OF_ranges, when parsing the ranges for MEM and I/O space, the res->start for mem is correctly set to ranges[na+2], which is the cpu address in the ranges property. However, in I/O related code, res->start is set to ranges[2], which is in the PCI address field of the ranges property (and in my case is 0, as is also for the mpc8272ads case as well). Thus, the res->start of the I/O of the bridge is 0, which leads to the first device with I/O space (a davicom ethernet device) been also assigned a I/O region starting at 0. Finally, the dmfe (davicom ethernet driver over PCI) fails with "dmfe: I/O base is zero". So, is the implementation of pci_process_bridge_OF_ranges correct ? shouldn't res->start = ranges[na+2] for I/O as well?
