Hi
This is a patch to add Luminary Micro LM3S9B90 and LM3S9B92 Evaluation
Kit support. These kits include a new ft2232 adapter, the Luminary
In-Circuit Debug Interface (ICDI) Board. So i added this as a new ft2232
layout, called "luminary_icdi".
The topic is discussed here:
https://lists.berlios.de/pipermail/openocd-development/2009-June/008880.html
Please apply this patch.
Best regards
Marcel
