You can find these files in the BSP Layer at:
meta-<bsp_name>/recipes-graphics/*
This optional directory contains recipes for the BSP if it has
special requirements for graphics support.
All files that are needed for the BSP to support a display are kept here.
For example, the Crown Bay BSP contains two versions of the
xorg.conf
file.
The version in crownbay
builds a BSP that supports the
Intel® Embedded Media Graphics Driver (EMGD),
while the version in crownbay-noemgd
builds
a BSP that supports Video Electronics Standards Association (VESA) graphics only:
