Thanks Liviu and Joseph. The ideal way to proceed would be to have Joseph sending one or two patches to OpenOCD Gerrit. But so far we have never received any direct contribute from arm employees, no idea if is there any real blocking point there.
I plan to work on C-M52 in the near future for adding the vector registers, but free time is never enough! If neither Joseph nor anyone else can push some patch with the info below, I can take them in my future patches, keeping the acknowledge to the sources of the information.
