it's good that you don't have that cruft :).  i've also found that many 
Blackfin linux drivers utilize IRQs/DMA heavily while the u-boot driver does 
polling/register banging.  sometimes this can make a huge difference to the 
code base, as well as hit a completely different set of issues (such as 
hardware or documentation bugs).
