David Brownell <david-b@pacbell.net> Accomodate targets which don't support various target-specific
reset operations. Maybe they can't; or it's a "not yet" thing. Note that the assert/deassert operations can't yet trigger for OMAP3 because resets currently include JTAG reset in all cases, resetting the ICEpick and thus disabling the TAP for Cortex-A8. git-svn-id: svn://svn.berlios.de/openocd/trunk@2620 b42882b7-edfa-0310-969c-e2dbd0fdcd60
