Hi!
Can somebody give me a hint: - what part of 2.6 (mips) code is responsible for setting i/o and memory space enable bits in PCI-PCI bridge config. space command register?
On my board those bits are not set after bridge is configured.
Currently I'm using the following change in "pcibios_enable_resources" to work with devices behind the bridge.

   pci_read_config_word(dev, PCI_COMMAND, &cmd);
   old_cmd = cmd;
-    for(idx=0; idx<6; idx++) {
+    for(idx=0; idx<=PCI_BRIDGE_RESOURCES; idx++) {
       /* Only set up the requested stuff */
       if (!(mask & (1<<idx)))
           continue;

but I think there should be some legal way I missed.
