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