Maybe it is a bit sub-optimal that the item shows up under the top level 
drivers group. Which is already pretty busy. Maybe on top something like:

diff --git a/drivers/Kconfig b/drivers/Kconfig
index 7c556c5ac4fd..c5edbd2288a1 100644

  endmenu


To move it under Device Drivers -> Graphics support? Give or take the 
exact positioning.
