- * cvmx_l2c_ctl
- *
- * L2C_CTL = L2C Control
- *
- *
- * 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.
