Subject: oe-selftest: fitimage: add machine-agnostic test-dtbs-as-ext recipe
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4817faa1d3cc676a8a7aa567f8e175ad9952b402;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

oe-selftest: fitimage: add machine-agnostic test-dtbs-as-ext recipe

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.
