 140         granularity is 1/4 cycle. For example, the value 0x05060606
 141         means that the delay is 5 quarter-cycles for one lane (1.25
 142         cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
 143         The default value 0 means autodetection. The results of hardware
 144         autodetection are not very reliable and depend on the chip
 145         temperature (sometimes producing different results on cold start
 146         and warm reboot). But the accuracy of hardware autodetection
 147         is usually good enough, unless running at really high DRAM
 148         clocks speeds (up to 600MHz). If unsure, keep as 0.
