47 Usually system firmware turns off system memory clock
48 signals to unused SO-DIMM slots to reduce EMI and power
49 consumption.
50 However, some boards do not like unused clock signals to
51 be disabled.

57 If non-zero, this designates the maximum DDR frequency
58 the board supports, despite what the chipset should be
59 capable of.

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