- added manpage for OpenOCD (thanks to Uwe Hermann)

- fixed bug in ARM926EJ-S cache handling that caused cache linefills to be disabled after first debug entry
- added support for auto image type detection (thanks to Vincent Palatin)
- further work on ETM trace decoding (tested with a ETB interface using an ETM in normal 16-bit port mode, still experimental)
