 - reset run/halt/step for arm926ejs is not robust. Needs lots of testing to
 map out problems.
 
+- i.MX27 reset run problems. Notice below that even if the target is running,
+a EICE_DBG_STATUS_DBGACK(I think...) is detected and OpenOCD wrongly believes that the
+target is halted. Polling the target afterwards reveals that the
+target is running. Notice the MOE=0xe value.
