+          On revisions of the PL310 prior to r3p2, the Store Buffer does
+          not automatically drain. This can cause normal, non-cacheable
+          writes to be retained when the memory system is idle, leading
+          to suboptimal I/O performance for drivers using coherent DMA.
+          This option adds a write barrier to the cpu_idle loop so that,
+          on systems with an outer cache, the store buffer is drained
+          explicitly.
