Hello Ian, welcome! Glad to hear about Cadence's interest in contributing to OpenOCD.
I'm reviewing the Expressif patches from Erhan, which clearly focus on Expressif implementation. You mentioned that the Cadence Xtensa port is based on the Expressif Xtensa solution. Do you think it's possible to proceed reviewing Erhan's code and then apply on top of it the extra Cadence code? I'm not used to Xtensa architecture, so my review will mainly focus on OpenOCD integration. Would you or some of your Xtensa experts contribute to the gerrit review for Expressif Xtensa code?
