From: Adrian Freihofer <[email protected]>
Add a minimal, fully standalone device-tree recipe for use by the
fitimage selftests. The two source files have no kernel-source
dependencies, so the recipe builds on any OE-core machine without
requiring a BSP layer.
test-ext.dts -- a tiny /dts-v1/ tree with a single aliases node and
an oe-selftest,test-ext compatible string.
test-overlay.dts -- a /plugin/ overlay referencing the root node.
COMPATIBLE_MACHINE = ".*" so the recipe is accepted on every target.
A test-ext-alias.dtb symlink is created in both do_install and
do_deploy (mirroring the alias pattern used by the external-DTB
fitimage tests) so that the configuration-node alias code path is
exercised.
