not really.  i highly doubt RTEMS has an audio stack let alone codec
drivers for the parts that are on the board.  so if you ignore those,
the software is exactly the same.

however, on the off chance RTEMS does support these codecs, it would
still need to dynamically detect whether the codecs are connected
(since the ezkit has switches to disconnect them from the
Blackfin/power).  in which case the BSP code would still be exactly
the same.
