openocd/src/flash/flash.c
drath 29000b204d - reworked presto.c to allow use of either FTD2XX or libftdi (libftdi not functional yet). Configure option changed from --enable-presto to
--enable-presto_ftd2xx and --enable-presto_libftdi
- completed trace point support for use with ARM7/9 DCC
- completed debug message output with support for HEX dumps (1, 2 or 4 byte quantities)
- fixed bug in delete_debug_msg_receiver (thanks to Pavel Chromy)
- fixed bug in image_add_section (thanks to Pavel Chromy)
- at91sam7 sector erase reworked (thanks to Pavel Chromy)
- merge consecutive sections during flash image write to work around possible section alignment issues with LPC2000 targets
