0073  * - Validate the required L2C bootloader settings.
0074  *
0075  *   - Check that the bootloader did set the L2CACCC.128WF register field.
0076  *
0077  *   - Check that the bootloader did clear the L2CACCC.DBPF register field.
0078  *
0079  *   - Check that the bootloader did set the L2CACCC.SPLIT register field.
0080  *
0081  *   - Check that the bootloader did clear the L2CERR.COMP register field.
