Comment (by Chris Johns):

 Replying to [comment:12 Sebastian Huber]:
 > In RTEMS 6, we have now a `RTEMS_PARTITION_ALIGNMENT` attribute for
 partition buffers. Enabling/disabling the GCC `-malign-int` option for
 ColdFire is something for RTEMS 7.

 I seem to remember an option like that being tested with MMS. I do not
 remember the results. Maybe Alan can remember?

 I updated the RSB so options could be passed in when building the tools
 for this testing.
