Some not critical changes, and a bit more testing was done (on ux164 - including card with an extra bridge, thanks to Michal). Changes from bridges-2.4.0t11-rth: - Disable devices before changing BARs - Handle bridges not supporting IO forwarding - Handle bridges with their own IO ports and/or memory - Set cache line and default latency for all devices - Updated comment for empty IO/memory ranges case Diffs against bridges-2.4.0t11-rth and pristine 2.4.0-test11 attached. Ivan.
