DDRLK
DDR Reset Lock:
0= Reset is asserted to the DDR DIMMs/devices normally.
1= Reset will not be asserted to the DDR DIMMs/devices. With proper DDR controller setup and careful
software setup DDR contents can survive resets.
This bit is not cleared with a general reset, but is preserved, as long as power is available. It is expected
that software that sets this bit is also responsible for clearing it.
