+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
+API and calling code. New API should cut down # of lines in calling
+code by 100's and make things clearer. Also potentially be supported
+directly in minidriver API for better embedded host performance.
