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.

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.
