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