- renamed M5960 USB JTAG to "flyswatter"
- make ep93xx and at91rm9200 bitbang JTAG interfaces dependant on ARM host (thanks to Vincent Palatin)
- various whitespace fixes
- removed various warnings
- add support for Debian GNU/kFreeBSD (thanks to Uwe Hermann)
- fix OpenOCD compilation for various platforms (thanks to Uwe Hermann and Vincent Palatin)
- switched order of JTAG chain examination and validation (examine first, then multiple validation tries even if examination failed)
- added target_request subsystem to handle requests from the target (debug messages and tracepoints implemented, future enhancements might include
semihosting, all ARM7/9 only for now)
- added support for GDB vFlashXXX packets (thanks to Pavel Chromy)
- added support for receiving data via ARM7/9 DCC
- reworked flash writing. the 'flash write' command is now deprecated and replaced by 'flash write_binary' (old syntax and behaviour) and 'flash
write_image' (write image files (bin, hex, elf, s19) to a target).
- added support for AMD/ST/SST 29F400B non-cfi flashes
