-# Exit requirements include:  (a) JTAG must be working, (b) the scan
-# chain was validated with "jtag arp_init" (or equivalent), (c) nothing
-# stays in reset.  No TAP-specific scans were performed.  It's OK if
-# some targets haven't been reset yet; they may need TAP-specific scans.
-#
-# The "mode" values include:  halt, init, run (from "reset" command);
-# startup (at OpenOCD server startup, when JTAG may not yet work); and
-# potentially more (for reset types like cold, warm, etc)
