+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.

+- ARM7/9:
+  - 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:
   - reset run/halt/step is not robust; needs testing to map out problems.
 - ARM11 improvements (MB?)
-  - fix single stepping  (reported by �H)
+  - fix single stepping  (reported by ØH). Need to automatically
+  use hardware stepping if available.
+  - hunt down and add timeouts to all infinite loops, e.g. arm11_run_instr_no_data would
+    lock up in infinite loop if e.g. an "mdh" command tries to read memory from invalid memory location.
+    Try mdh 0x40000000 on i.MX31 PDK
+  - mdb can return garbage data if read byte operation fails for
+  a memory region(16 & 32 byte access modes may be supported). Is this
+  a bug in the .MX31 PDK init script? Try on i.MX31 PDK: 
+  mdw 0xb80005f0 0x8, mdh 0xb80005f0 0x10, mdb 0xb80005f0 0x20. mdb returns
+  garabage.
   - implement missing functionality (grep FNC_INFO_NOTIMPLEMENTED ...)
+  - thumb support is missing: ISTR ARMv6 requires Thumb.
+  ARM1156 has Thumb2; ARM1136 doesn't.
 - Cortex A8 support (ML)
   - add target implementation (ML)
+- Generic ARM run_algorithm() interface
+  - tagged struct wrapping ARM instructions and metadata
+  - not revision-specific (current: ARMv4+ARMv5 -or- ARMv6 -or- ARMv7)
+  - usable with at least arm_nandwrite() and generic CFI drivers
 - MC1322x support (JW/DE?)
   - integrate and test support from JW (and DE?)
   - get working with a known good interface (i.e. not today's jlink)
