where to find "drivers/video/da8xx-fb.c" in /setup-scripts

Hi,

I was able to compile angstrom build.
I need to change the frame buffer to support PICO projector in beagle bone.

I’m unable to find

drivers/video/da8xx-fb.c

Can you please help me trace this file ?.

Thanks,
Aravind.

Pay special attention to the 'kernel workflow' one. It's also linked from the angstrom website frontpage.
