+ * (ORx, BRx, P/LSDMR). After all memory parameters are configured,
+ * system software should execute the following initialization sequence
+ * for each SDRAM device.
+ *
+ * 1. Issue a PRECHARGE-ALL-BANKS command
+ * 2. Issue eight CBR REFRESH commands
+ * 3. Issue a MODE-SET command to initialize the mode register
+ *
+ * The initial commands are executed by setting P/LSDMR[OP] and
+ * accessing the SDRAM with a single-byte transaction."
+ *
+ * The appropriate BRx/ORx registers have already been set when we
+ * get here. The SDRAM can be accessed at the address CFG_SDRAM_BASE.
