+ The PL310 L2 cache controller implements three types of Clean &
+ Invalidate maintenance operations: by Physical Address
+ (offset 0x7F0), by Index/Way (0x7F8) and by Way (0x7FC).
+ They are architecturally defined to behave as the execution of a
+ clean operation followed immediately by an invalidate operation,
+ both performing to the same memory location. This functionality
+ is not correctly implemented in PL310 as clean lines are not
+ invalidated as a result of these operations. Note that this errata
