+ *	       Source: Calculation based on board trace lengths and
+ *		       chip-specific internal delays.
+ *     2.) CLK_ADJUST (Clock and Addr/Cmd alignment control)
+ *	       - DDR_SDRAM_CLK_CNTL register
+ *	       Source: Signal Integrity Simulations
+ *     3.) 2T Timing on Addr/Ctl
+ *	       - TIMING_CFG_2 register
+ *	       Source: Signal Integrity Simulations
+ *	       Usually only needed with heavy load/very high speed (>DDR2-800)
