+     *
+     * "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 CFG_SDRAM_BASE.
