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.
