Remap Base (REMAPBASE_0_0_0_MCHBAR) – Offset D890
The value in this register defines the lower boundary of the Remap window.
The Remap window is inclusive of this address.
In the decoder A[19:0] of the Remap Base Address are assumed to be 0's.
Thus the bottom of the defined memory range will be aligned to a 1MB boundary.
When the value in this register is greater than the value programmed into the Remap Limit register, the Remap window is disabled.
These bits are Intel TXT lockable.
