liveupdate: remove liveupdate_test_unregister()

2026-04-18T07:10:50Z

Now that file handler unregistration automatically unregisters all associated file handlers (FLBs), the liveupdate_test_unregister() function is no longer needed. Remove it along with its usages and declarations.

tests/liveupdate: add in-kernel liveupdate test

2026-02-08T08:13:33Z

Introduce an in-kernel test module to validate the core logic of the Live Update Orchestrator's File-Lifecycle-Bound feature. This provides a low-level, controlled environment to test FLB registration and callback invocation without requiring userspace interaction or actual kexec reboots. The test is enabled by the CONFIG_LIVEUPDATE_TEST Kconfig option.
