This is great. So far, we have not seen any MT622x based phone that has JTAG exposed.
Well, there is the CECT C3100 which has JTAG solder pads. OpenOCD successfully detected the CPU, but I couldn't halt the ARM core (same problem on the Calypso btw). I tried other random ARM7 targets which had the same EmbeddedICE revision and there it worked.
Did you check the config? I've seen bad reset signal settings in tcl/target/*.cfg (trst/srst) which stopped me from getting proper control over the core.
