Graphics Stolen Memory and Tseg are within DRAM space defined under TOLUD. From 
the top of low used DRAM, CPU Uncore claims 1 to 64MBs of DRAM for internal 
graphics if enabled. 
The base of stolen memory will always be below 4G. This is required to prevent 
aliasing between  stolen range and the reclaim region.

Base of Stolen Memory  (BSM):  
 This register contains bits 31 to 20 of the base 
address of stolen DRAM memory. The host 
interface determines the base of Graphics Stolen 
memory by subtracting the graphics stolen 
memory size from TOLUD. See Device 0 TOLUD 
for more explanation.
