187 means that the delay is 5 quarter-cycles for one lane (1.25
188 cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
189 The default value 0 means autodetection. The results of hardware
190 autodetection are not very reliable and depend on the chip
191 temperature (sometimes producing different results on cold start
192 and warm reboot). But the accuracy of hardware autodetection
193 is usually good enough, unless running at really high DRAM
