- * "At system reset, initialization software must set up the
- * programmable parameters in the memory controller banks registers
- * (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 CONFIG_SYS_SDRAM_BASE.
