MH1_DIMM_CID (mh1_dimm_cid):
Hottest DIMM Channel ID for MEM_HOT[1]#. PCU microcode search the 
hottest DIMM temperature and write the hottest temperature and the 
corresponding Hottest DIMM CID/ID.

MH1_DIMM_ID (mh1_dimm_id):
Hottest DIMM ID for MEM_HOT[1]#. PCU microcode search the hottest 
DIMM temperature and write the hottest temperature and the 
corresponding Hottest DIMM CID/ID.

MH1_TEMP (mh1_temp):
Hottest DIMM Sensor Reading for MEM_HOT[1]# - This reading represents 
the temperature of the hottest DIMM. PCU microcode search the hottest 
DIMM temperature and write the hottest temperature and the 
corresponding Hottest DIMM CID/ID. Note: iMC hardware load this value 
into the MEMHOT duty cycle generator counter since PCU microcode may 
update this field at different rate/time. This field is ranged from 0 to 127, 
i.e. the most significant bit is always zero.

MH0_DIMM_VAL (mh0_dimm_val):
Valid if set. PCU microcode search the hottest DIMM temperature and write 
the hottest temperature and the corresponding Hottest DIMM CID/ID and 
set the valid bit. MEMHOT hardware logic process the corresponding 
MEMHOT data when there is a MEMHOT event. Upon processing, the valid 
bit is reset. PCU microcode can write over existing valid temperature since a 
valid temperature may not occur during a MEMHOT event. If PCU microcode 
set the valid bit occur at the same cycle that the MEMHOT logic processing 
and try to clear, the PCU microcode set will dominate since it is a new 
temperature is updated while processing logic tries to clear an existing 
temperature.

MH0_DIMM_CID (mh0_dimm_cid):
Hottest DIMM Channel ID for MEM_HOT[0]#. PCU microcode search the 
hottest DIMM temperature and write the hottest temperature and the 
corresponding Hottest DIMM CID/ID.
