MESEG_MASK—Intel Management Engine Limit Address  
Register  
This register determines the Mask Address register of the memory range that is pre-  
allocated to the Intel Management Engine. Together with the MESEG_BASE register it  
controls the amount of memory allocated to the ME.  
This register is locked by Intel TXT.  
Note:  
BIOS must program MESEG_BASE and MESEG_MASK so that Intel ME stolen Memory is  
carved out from TOM.

ME UMA Memory Mask (MEMASK)  
This field indicates the bits that must match MEBASE in order to  
qualify as an Intel MEMemory Range access.  
For example, if the field is set to 7FFFFh, then Intel MEMemory is  
1 MB in size.

Another example is that if the field is set to 7FFFEh, then Intel  
MEMemory is 2 MB in size.  
In other words, the size of Intel MEMemory Range is limited to  
power of 2 times 1 MB.
