+ * Notes:
+ * (1) If MAXVAB is != 0, VAB_THRESH should be less than MAXVAB.
+ *
+ * (2) L2DFDBE and L2DFSBE allows software to generate L2DSBE, L2DDBE, VBFSBE,
+ * and VBFDBE errors for the purposes of testing error handling code. When
+ * one (or both) of these bits are set a PL2 which misses in the L2 will fill
+ * with the appropriate error in the first 2 OWs of the fill. Software can
+ * determine which OW pair gets the error by choosing the desired fill order
+ * (address<6:5>). A PL2 which hits in the L2 will not inject any errors.
+ * Therefore sending a WBIL2 prior to the PL2 is recommended to make a miss
+ * likely (if multiple processors are involved software must be careful to be
+ * sure no other processor or IO device can bring the block into the L2).
+ *
+ * To generate a VBFSBE or VBFDBE, software must first get the cache block
+ * into the cache with an error using a PL2 which misses the L2. Then a
+ * store partial to a portion of the cache block without the error must
+ * change the block to dirty. Then, a subsequent WBL2/WBIL2/victim will
+ * trigger the VBFSBE/VBFDBE error.
