 - 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
+  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.
