+ * - Validate the required L2C bootloader settings.
+ *
+ *   - Check that the bootloader did set the L2CACCC.128WF register field.
+ *
+ *   - Check that the bootloader did clear the L2CACCC.DBPF register field.
+ *
+ *   - Check that the bootloader did set the L2CACCC.SPLIT register field.
+ *
+ *   - Check that the bootloader did clear the L2CERR.COMP register field.
