This register determines the size of the graphics memory aperture in function 0 and in
the trusted space. Only the system BIOS will write this register based on pre- boot
address allocation efforts, but the graphics may read this register to determine the
correct aperture size. System BIOS needs to save this value on boot so that it can
reset it correctly during S3 resume.
