The K230 machine supports direct Linux boot and firmware boot through the SDK U-Boot, but neither path has functional test coverage. Add one test for each boot path. Both tests use the Yocto initramfs assets and wait for the shell prompt to confirm a successful boot. Fetch the boot assets from the k230-boot-assets repository maintained by Chao Liu. Pin the URLs to a repository commit and verify each asset with its SHA-256 digest.
