Processor Configuration Registers 

This register determines the Base Address register of the memory range that is pre-
allocated to the Intel Management Engine. Together with the MESEG_MASK register it 
controls the amount of memory allocated to the ME.

This register must be initialized by the configuration software. For the purpose of 
address decode, address bits A[19:0] are assumed to be 0. Thus, the bottom of the 
defined memory address range will be aligned to a 1 MB boundary.

This register is locked by Intel TXT.

BIOS must program MESEG_BASE and MESEG_MASK so that Intel ME stolen Memory is 

carved out from TOM.
