+ * This is 1.56 clock cycles, pick CPO = READ_LAT + 3/2 (0x8)
+ *
+ * Write latency (WR_DATA_DELAY) is calculated by doing the following:
+ *
+ * The DDR SDRAM specification requires DQS be received no sooner than
+ * 75% of an SDRAM clock period—and no later than 125% of a clock
+ * period—from the capturing clock edge of the command/address at the
+ * SDRAM.
+ *
+ * Based on the above tracelengths, the following are calculated:
+ * Ch. 0 8572 to DRAM propagation (DQ lanes) : 1.9" * 180 = 0.342ns
+ * Ch. 0 8572 to DRAM propagation (CLKs) : 2.3" * 180 = 0.414ns
+ * Ch. 1 8572 to DRAM propagation (DQ lanes) : 0.7" * 180 = 0.126ns
+ * Ch. 1 8572 to DRAM propagation (CLKs ) : 1.47" * 180 = 0.264ns
+ *
+ * Difference in arrival time CLK vs. DQS:
+ * Ch. 0 0.072ns
+ * Ch. 1 0.138ns
+ *
+ * Both of these values are much less than 25% of the clock
+ * period at DDR2-600 or DDR2-800, so no additional delay is needed over
+ * the 1/2 cycle which normally aligns the first DQS transition
+ * exactly WL (CAS latency minus one cycle) after the CAS strobe.
+ * See Figure 9-53 in MPC8572E manual: "1/2 delay" in Freescale's
+ * terminology corresponds to exactly one clock period delay after
+ * the CAS strobe. (due to the fact that the "delay" is referenced
+ * from the *falling* edge of the CLK, just after the rising edge
+ * which the CAS strobe is latched on.
