Add a new test function which checks that the device-tree of U-Boot
contains the public keys which are required for checking the signature
of the kernel FIT image at run-time.
Use this new _check_kernel_dtb function in the existing
test_sign_cascaded_uboot_fit_image test case which already creates a
build configuration with UBOOT_SIGN_ENABLE = "1" and keys for the kernel.
But so far there was no check that the keys for the kernel verification
got added to U-Boot's DTB.
This test case checks the configuration where only the configuration
nodes of the kernel FIT image are signed.
A new test case test_sign_uboot_kernel_individual checks the
configuration with two keys and signed image and signed configuration
nodes.
This test case covers the use case which recently broke with commit:
OE-Core rev: 259bfa86f384206f0d0a96a5b84887186c5f689e
u-boot: kernel-fitimage: Fix dependency loop if
UBOOT_SIGN_ENABLE and UBOOT_ENV enabled
and got fixed with commit
OE-Core rev: 0106e5efab99c8016836a2ab71e2327ce58a9a9d
u-boot: kernel-fitimage: Restore FIT_SIGN_INDIVIDUAL="1"
behavior
This patch also fixes a few more details:
- Simplify the code by moving all the U-Boot related variables to the
_fit_get_bb_vars function.
- Do not set FIT_GENERATE_KEYS = "1" without inheriting the
kernel-fitimage.bbclass which handles this variable.

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
