+ * Bits for the SDRAM controller
+ * -----------------------------
+ *
+ * CAL: CAS Latency. If cleared to 0 (default) the SDRAM controller asserts TA# on
+ * the 2nd Clock after ACTIVE command (CAS Latency = 2). If set to 1 the SDRAM
+ * controller asserts TA# on the 3rd Clock after ACTIVE command (CAS Latency = 3).
+ * RCD: RCD ACTIVE to READ or WRITE Delay (Ras to Cas Delay). If cleared 0 (default)
+ * tRCD of the SDRAM must equal or less 25ns. If set to 1 tRCD must be equal or less 50ns.
+ * WREC:Write Recovery. If cleared 0 (default) tWR of the SDRAM must equal or less 25ns.
+ * If set to 1 tWR must be equal or less 50ns.
+ * RP: Precharge Command Time. If cleared 0 (default) tRP of the SDRAM must equal or less
+ * 25ns. If set to 1 tRP must be equal or less 50ns.
+ * RC: Auto Refresh to Active Time. If cleared 0 (default) tRC of the SDRAM must equal
+ * or less 75ns. If set to 1 tRC must be equal or less 100ns.
+ * LMR: Bit to set the Mode Register of the SDRAM. If set, the next access to the SDRAM
+ * is the Load Mode Register Command.
+ * IIP: Init in progress. Set to 1 for starting the init sequence
+ * (Precharge All). As long this bit is set, the Precharge All is still in progress.
+ * After command has completed, wait at least for 8 refresh (200usec) before proceed.
