Hostboot (Hostboot): Open-source boot firmware used to boot OpenPOWER systems since POWER8. It is started running by the SBE after it completes its own initialization tasks, and is the first code that executes on the main POWER cores (all earlier stages execute on auxillary PPE cores). It is responsible for memory initialization and other tasks. It finishes by chainloading Skiboot.
