44# Apply overlays statically with fdtoverlay.  This is a build time test that
45# the overlays can be applied successfully by fdtoverlay.  This does not
46# guarantee that the overlays can be applied successfully at run time by
47# unittest, but it provides a bit of build time test coverage for those
48# who do not execute unittest.
49#
50# The overlays are applied on top of static_base_1.dtb and static_base_2.dtb to
51# create static_test_1.dtb and static_test_2.dtb.  If fdtoverlay detects an
52# error than the kernel build will fail.  static_test_1.dtb and
53# static_test_2.dtb are not consumed by unittest.
54#
55# Some unittest overlays deliberately contain errors that unittest checks for.
56# These overlays will cause fdtoverlay to fail, and are thus not included
57# in the static test:
