Remap Base Address (REMAPBASE)
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 0s. Thus the bottom of the defined memory range will be
aligned to a 1 MB 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.
