- * Quote from 8260 UM (10.4.2 SDRAM Power-On Initialization, 10-35):
- *
- * "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
- *
- * Quote from Micron MT48LC8M16A2 data sheet:
- *
- * "...the SDRAM requires a 100uS delay prior to issuing any
- * command other than a COMMAND INHIBIT or NOP. Starting at some
- * point during this 100uS period and continuing at least through
- * the end of this period, COMMAND INHIBIT or NOP commands should
- * be applied."
- *
- * "Once the 100uS delay has been satisfied with at least one COMMAND
- * INHIBIT or NOP command having been applied, a /PRECHARGE command/
- * should be applied. All banks must then be precharged, thereby
- * placing the device in the all banks idle state."
- *
- * "Once in the idle state, /two/ AUTO REFRESH cycles must be
- * performed. After the AUTO REFRESH cycles are complete, the
- * SDRAM is ready for mode register programming."
- *
- * (/emphasis/ mine, gvb)
- *
- * The way I interpret this, Micron start up sequence is:
- * 1. Issue a PRECHARGE-BANK command (initial precharge)
- * 2. Issue a PRECHARGE-ALL-BANKS command ("all banks ... precharged")
- * 3. Issue two (presumably, doing eight is OK) CBR REFRESH commands
- * 4. 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.
