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
- usbprog.c
- vsllink.c
- rlink/rlink.c
+- bug: USBprog is broken with new tms sequence; it needs 7-clock cycles.
+ Fix promised from Peter Denison openwrt at marshadder.org
+ Workaround: use "tms_sequence long" @par

- add reset option to allow programming embedded ice while srst is asserted.
Some CPUs will gate the JTAG clock when srst is asserted and in this case,
it is necessary to program embedded ice and then assert srst afterwards.
-- ARM923EJS:
+- ARM926EJS:
- reset run/halt/step is not robust; needs testing to map out problems.
- ARM11 improvements (MB?)
- add support for asserting srst to reset the core.
