|
|
||||||
*
|
|
||||||
* "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.
