chosen to be a NOP in one mode and a branch in the other, so the
code would only be executed if not already in AArch64.
This allows both the SPL and the U-Boot proper to be entered in
either mode and switch to AArch64 if needed.

Set the dram controller tpr3 parameter. This parameter configures

Set the dram controller dqs_gating_delay parmeter. Each byte
encodes the DQS gating delay for each byte lane. The delay
granularity is 1/4 cycle. For example, the value 0x05060606
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.
