However, loadcepc is just one implementation of a bootloader. There is no
mechanism provided by CE to do this task, and bootloaders are not standard.
This will also depend on how the OS image is stored, whether it's going to
be executed in place in flash, downloaded via some mechanism into RAM etc.
