 Probably we (me and Ilya) overdone with posting katmai.dts-related 
changes to ML, and duplicated the same patches in different posts. 
Sorry for the confusion. These nodes are necessary for the ppc440spe 
ADMA driver:

 No, we just selected the description which looked more appropriate 
for our case: SysAce is connected to the External Bus Controller of 
440SPe, which in turns is attached as a slave to OPB (on-chip 
peripheral).
