Thanks for agreeing to mentor!
I'm in the background research phase and have read the framebuffer manual
in the docs
and have seen the implementation in the RPi. I couldn't find a lot of
information of the FB
for Beaglebone Black, I'm currently looking at the code in
Beagleboard/linux repo.
Are there any suggested readings that will help me get a better
understanding of the
implementation? Also, it would be nice to have someone hint on the
_workflow_ of writing
the framebuffer driver for a BSP.
