Thermal Memory Map Base Address (TMMBA):
This field corresponds to bits 31 to 15 of the base address TMBAR address 
space.
BIOS will program this register resulting in a base address for a 32KB block of 
contiguous memory address space. This register ensures that a naturally 
aligned 32KB space is allocated within total addressable memory space.
