- *
- * II. Because you are using auto-precharge globally and want to
- * use additive latency (posted CAS) to get more bandwidth.
- * 1. Are you going to use auto-precharge mode globally?
- *
- * Use addtivie latency and compute AL to be 1 cycle less than
- * tRCD, i.e. the READ or WRITE command is in the cycle
- * immediately following the ACTIVATE command..
- *
- * III. Because you feel like it or want to do some sort of

- * ASSUMPTIONS:
- * - Same number of CONFIG_DIMM_SLOTS_PER_CTLR on each controller
- * - Same memory data bus width on all controllers
- *
- * NOTES:
- *
- * The memory controller and associated documentation use confusing
- * terminology when referring to the orgranization of DRAM.
- *
- * Here is a terminology translation table:
- *
- * memory controller/documention |industry |this code |signals
- * -------------------------------|-----------|-----------|-----------------
- * physical bank/bank |rank |rank |chip select (CS)
- * logical bank/sub-bank |bank |bank |bank address (BA)
- * page/row |row |page |row address
- * ??? |column |column |column address
- *
- * The naming confusion is further exacerbated by the descriptions of the
- * memory controller interleaving feature, where accesses are interleaved
- * _BETWEEN_ two seperate memory controllers. This is configured only in
- * CS0_CONFIG[INTLV_CTL] of each memory controller.
- *
- * memory controller documentation | number of chip selects
- * | per memory controller supported
- * --------------------------------|-----------------------------------------
- * cache line interleaving | 1 (CS0 only)
- * page interleaving | 1 (CS0 only)
- * bank interleaving | 1 (CS0 only)
- * superbank interleraving | depends on bank (chip select)
- * | interleraving [rank interleaving]
- * | mode used on every memory controller
- *
- * Even further confusing is the existence of the interleaving feature
- * _WITHIN_ each memory controller. The feature is referred to in
- * documentation as chip select interleaving or bank interleaving,
- * although it is configured in the DDR_SDRAM_CFG field.
- *
- * Name of field | documentation name | this code
- * -----------------------------|-----------------------|------------------
- * DDR_SDRAM_CFG[BA_INTLV_CTL] | Bank (chip select) | rank interleaving
- * | interleaving
