Hi all,

I am writing framebuffer driver using SM501. This graphics driver chip can
drive CRT and TFT panel. I have written two seperate framebuffer driver, one
for CRT and one for TFT Panel.

But I am not able to test both the devices. Any one of them work at a time.
I have created two files /dev/fb0 and /dev/fb1. These two can be open
successfully and mmap is also successful from userspace. If I am trying to
write on fb0 and  fb1 with different data, they displayed on either CRT or
TFT panel.

Can any one help me How to test two different framebuffer devices?
