16 * Enable cluster-level coherency, in preparation for turning on the MMU.
17 * The ACTLR SMP bit does not need to be set here, because cpu_resume()
18 * already restores that.
20 * A15/A7 may not require explicit L2 invalidation on reset, dependent
21 * on hardware integration decisions.
22 * For now, this code assumes that L2 is either already invalidated,
23 * or invalidation is not required.
