- two flavors of the controller 'outer cache' and 'system cache' (the
last one meaning maintenance operations on L1 are broadcasted to the
L2 and L2 performs the same operation).
BTW, is the DSB also transparently handled by the L2 in 'system cache' mode?
The information I have is that from the point view of the software
there is no need to take any extra actions when using this kind of
command, everything is handle by the hardware. So I guess that the
answer to your question should be yes.
