58 Usually system firmware turns off system memory clock
59 signals to unused SO-DIMM slots to reduce EMI and power
60 consumption.
61 However, some boards do not like unused clock signals to
62 be disabled.

68 If non-zero, this designates the maximum DDR frequency
69 the board supports, despite what the chipset should be
70 capable of.

75 On some boards it may be neccessary to hard reset early
76 during resume from S3 if the SLFRCS register indicates that
77 a memory channel is not guaranteed to be in self-refresh.
78 On other boards the check always creates a false positive,
79 effectively making it impossible to resume.
