If an rn50/r100/m6/m7 GPU has < 64MB RAM, i.e. 8/16/32, the aperture used to calculate the MC_FB_LOCATION needs to be worked out from the CONFIG_APER_SIZE register, and not the actual vram size. TTM VRAM size was also being initialised wrong, use actual vram size to initialise it. Signed-off-by: Dave Airlie <airlied@redhat.com>
