Use
The unified cache or data cache are to be globally cleaned (any writeback data updated to memory). Invalidation is not required.
Notes
Note that any write buffer draining will also be performed by this operation, so that memory is fully updated with respect to any writeback data.
The OS only expects the cleaning to be with respect to data that are not involved in any currently active interrupts.
