I'm not familiar with SH hardware so wasn't sure if there was some other application you had for the multiple regions. - k -- To unsubscribe from this list: send the line unsubscribe linux-embedded in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

One topic that was partially touched on was dealing with various memories on embedded systems.
