commit 07f86917a450 used shared-dma-pool for QMan private memory 
allocations and

added this warning, but this is only for non-PPC platforms and using non 
shared-dma-mem

reservations. However, for non-PPC platforms, commit 3e62273ac63a will 
output a warning anyway.


At the same time, ls1043 already uses shared-dma-mem, so is this warning 
still necessary?


thanks
