# Kernel configuration and dts specific information

#
# Kernel configurations and dts (If not using Linux provided ones) are captured
# in this file. Update SRC_URI and do_patch for building images with custom dts
#

# We can't set FILESEXTRAPATHS once because of how the kernel classes search for
# config fragments. Discussion is ongoing as to whether this is the correct
# solution, or a workaround.
