The Extended SMRAM register controls the configuration of Extended SMRAM space.
The Extended SMRAM (E_SMRAM) memory provides a write-back cacheable SMRAM
memory space that is above 1 MB.

Enable High SMRAM (H_SMRAME):
above 1 MB or below 1 MB) When G_SMRAME is
1 and H_SMRAME is set to 1, the high SMRAM
memory space is enabled. SMRAM accesses
within the range 0FEDA0000h to 0FEDBFFFFh
are remapped to DRAM addresses within the
range 000A0000h to 000BFFFFh. Once D_LCK
has been set, this bit becomes read only.
Invalid SMRAM Access (E_SMERR):
defined memory ranges in Extended SMRAM
(High Memory and T-segment) while not in SMM
space and with the D-OPEN bit = 0. It is
software's responsibility to clear this bit. The
software must write a 1 to this bit to clear it.
SMRAM Cacheable (SM_CACHE):
This bit is forced to '1' by the CPU Uncore.
L1 Cache Enable for SMRAM (SM_L1):
This bit is forced to '1' by the CPU Uncore.
L2 Cache Enable for SMRAM (SM_L2):
TSEG Size (TSEG_SZ):
enabled. Memory from the top of DRAM space is
partitioned away so that it may only be accessed
by the processor interface and only then when
the SMM bit is set in the request packet. Non-
SMM accesses to this memory region are sent to
DMI when the TSEG memory block is enabled.
