- endianess fixes everywhere but in the flash code. flashing might still be broken on big-endian targets and/or hosts
- added access to ARM920T vector catch register (via generic register mechanism)
- don't disable linefills on ARM920T cores - this lead to lockups when accessing lines already contained in cache
- read content of ARM920T cache and tlb into file (arm920t read_flash/read_mmu commands)
- memory reading improved on ARM7/9, can be further accelerated with new "arm7_9 fast_memory_access enable" command (renamed from fast_writes)
- made in_handler independent from in field (makes the handler more flexible)
- added timeout to ft2232 when using D2XX library
- fixed STR7x protection bit handling on second bank (thanks to Bernard)
- added support for using the OpenOCD on AT91RM9200 systems (thanks to Anders Larsen)
- fixed AT91SAM7 flash handling when not running from 32kHz clock (thanks to Anders Larsen)
