 - ARM923EJS:
   - reset run/halt/step is not robust; needs testing to map out problems.
 - ARM11 improvements (MB?)
-  - fix single stepping  (reported by ØH). Michael Bruck explained
-  that what's required is to emulate the current instruction(just like the
-  arm7 code) to know what address to set the breakpoint at for single
-  stepping an instruction.
+  - 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

   - 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)
