-+ *
-+ * Errata:
-+ * 588369: PL310 R0P0->R1P0, fixed R2P0.
-+ * Affects: all clean+invalidate operations
-+ * clean and invalidate skips the invalidate step, so we need to issue
-+ * separate operations. We also require the above debug workaround
-+ * enclosing this code fragment on affected parts. On unaffected parts,
-+ * we must not use this workaround without the debug register writes
-+ * to avoid exposing a problem similar to 727915.
-+ *
-+ * 727915: PL310 R2P0->R3P0, fixed R3P1.
-+ * Affects: clean+invalidate by way
-+ * clean and invalidate by way runs in the background, and a store can
-+ * hit the line between the clean operation and invalidate operation,
-+ * resulting in the store being lost.
-+ *
-+ * 752271: PL310 R3P0->R3P1-50REL0, fixed R3P2.
-+ * Affects: 8x64-bit (double fill) line fetches
-+ * double fill line fetches can fail to cause dirty data to be evicted
-+ * from the cache before the new data overwrites the second line.
-+ *
-+ * 753970: PL310 R3P0, fixed R3P1.
-+ * Affects: sync
-+ * prevents merging writes after the sync operation, until another L2C
-+ * operation is performed (or a number of other conditions.)
-+ *
-+ * 769419: PL310 R0P0->R3P1, fixed R3P2.
-+ * Affects: store buffer

-+ 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

-+ is not correctly implemented in PL310 as clean lines are not
-+ invalidated as a result of these operations.

-+ depends on CACHE_L2X0
-+ help
-+ PL310 implements the Clean & Invalidate by Way L2 cache maintenance
-+ operation (offset 0x7FC). This operation runs in background so that
-+ PL310 can handle normal accesses while it is in progress. Under very
-+ rare circumstances, due to this erratum, write data can be lost when

-+ help
-+ This option enables the workaround for the 753970 PL310 (r3p0) erratum.
-+
-+ 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.

-+ help
-+ 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
