Subject: fbdev: detect primary display device
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
Add function helper, fb_is_primary_device(). Given struct fb_info, it will
return a nonzero value if the device is the primary display.
Currently, only the i386 is supported where the function checks for the
IORESOURCE_ROM_SHADOW flag.
