-+
-+	  Under some condition the effect of cache sync operation on
-+	  the store buffer still remains when the operation completes.
-+	  This means that the store buffer is always asked to drain and
-+	  this prevents it from merging any further writes. The workaround
-+	  is to replace the normal offset of cache sync operation (0x730)
-+	  by another offset targeting an unmapped PL310 register 0x740.
-+	  This has the same effect as the cache sync operation: store buffer
-+	  drain and waiting for all buffers empty.

-+	  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,
