- flash autoerase <on|off> cmd added, default is off - flash banks are calculated and erased prior to write (flash write_image only)
- corrected array overrun in armv7m.c - corrected breakpoint memory allocation bug - image read now uses fgets, vastly improves reading of large files - improved hex file reading, support for Linear Address Record added git-svn-id: svn://svn.berlios.de/openocd/trunk@208 b42882b7-edfa-0310-969c-e2dbd0fdcd60
