[U-Boot] Question about member fb_base of the global_data structure

Hi,

today I stumbled over the 'struct global_data' member 'fb_base'. It seems
that this variable is only used by two drivers:

./board/trab/vfd.c
./cpu/mpc8xx/video.c

There are also a few boards, wich print the content of fb_base to the 
console, but do not use it otherwise.

What was the intention behind fb_base? I assume, the framebuffer address
should be stored at a global place, so that everyone has access to it.
But why is it then not used by more boards?

Best Regards,
Martin
