+ Summary: Verifies the content of the initramfs bundle node in the FIT Image Tree Source (its)
+ The FIT settings are set by the test case.
+ The machine used is beaglebone-yocto.
+ Expected: 1. The ITS is generated with initramfs bundle support
+ 2. All the fields in the kernel node are as expected (matching the
+ conf settings)
+ 3. The kernel is included in all the available configurations and
+ its hash is included in the configuration signature
