 	means that the delay is 5 quarter-cycles for one lane (1.25
 	cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
 	The default value 0 means autodetection. The results of hardware
 	autodetection are not very reliable and depend on the chip
 	temperature (sometimes producing different results on cold start
 	and warm reboot). But the accuracy of hardware autodetection
 	is usually good enough, unless running at really high DRAM
 	clocks speeds (up to 600MHz). If unsure, keep as 0.
