Patch by Michael Schwingen that
- adds support for the Altium universal JTAG cable - adds support for "wiggler2" cable (basically a wiggler with added LED, documentation coming soon) - adds LED support. The LED is turned on during data transfer - works fine on Altium and wiggler2. - adds PORT_EXIT pattern that is written to port when exiting, in order to turn off power on cables that get their power from parallel port data lines - move port writes (with the system-specific ifdefs) to one central function - increased image cache size to 2KB (might require more adaptive cache handling, e.g. LRU) git-svn-id: svn://svn.berlios.de/openocd/trunk@204 b42882b7-edfa-0310-969c-e2dbd0fdcd60
