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