 The following tasks have been suggested for cleaning up the JTAG layer:
 
 - use tap_set_state everywhere to allow logging TAP state transitions
-- rename other tap_states to use standard JTAG names (suggested by ML)
 - Encapsulate cmd_queue_cur_state and related varaible handling.
 - add slick 32 bit versions of jtag_add_xxx_scan() that avoids
 buf_set_u32() calls and other evidence of poor impedance match between

 The following tasks have been suggested for adding new JTAG interfaces:
 
 - TCP driver: allow client/server for remote JTAG interface control.
+This requires a client and a server. The server is built into the
+normal OpenOCD and takes commands from the client and executes
+them on the interface returning the result of TCP/IP. The client
+is an OpenOCD which is built with a TCP/IP minidriver. The use

+fn's at a high enough level and repackage these cmd's as
+TCP/IP packets handled by the server.
