-  Title:       I2C TOOL PATITIONING
-  Description: The tool at apps/system/i2c makes direct calls into MCU level
-               I2C logic within the OS and, hence, violates the OS/application
-               interface.  An I2C character driver will need to be developed
-               to perform the I2C interactions within the OS; the I2C tools
-               will need to be modified to use that driver to perform the
-               I2C accesses.
-  Status:      Open
-  Priority:    Medium.  Until this change is made, the I2C tool will not be
-               availabel in protected or kernel builds.
   Title:       C++ CONSTRUCTORS HAVE TOO MANY PRIVILEGES (PROTECTED MODE)
   Description: When a C++ ELF module is loaded, its C++ constructors are called
                via sched/task_starthook.c logic.  This logic runs in protected mode.
