David Brownell <david-b@pacbell.net>:
Let disabled targets be ignored during normal operation: - In target_examine(), ignore disabled TAPs - Reset handling must not poke at them either: * fail $target_name arp_* operations on disabled TAPs * in startup.tcl, don't even issue the arp_* wait ops ZW: removed superfluous braces from the patch to target.c. git-svn-id: svn://svn.berlios.de/openocd/trunk@2100 b42882b7-edfa-0310-969c-e2dbd0fdcd60
