data & unified cache

In the A8 cache registers i see that the data cache tied to Unified cache - for enabling, cleaning etc. Any reason for this?

What do you mean by "tied to"? You can do cache maintenance on the L1 without explicitly impacting the L2 (there will be impacting side effects from any line evictions from the L1 of course).
