I'm fine with your decision, it was just a convenience for me, so I'll
keep it in my local tree, but I would ask in the context of u-boot
where there are essentially no 'services' or state that needs to be
saved, what's the real difference?

For a hypothetical do_reboot(), I suppose one could extract some of
the code of do_bootm() (shut off interrupts, usb, maybe caches) into a
common function, run an optional platform hook and then do_reset(),
but it doesn't seem like it would make much difference for the vast
majority of cases, once the hardware reset comes through.
