- * 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
