Dear Wolfgang Denk,

Sure!!! :)

Given that z_error is invoked by Assert macro (never used) and that "exit"
function (other than closing all
opened stream) will terminate program execution, I suggest to remove it
without adding others instructions letting
u-boot to hang by itself (if it will do this).

What's your idea?
Thanks,
Giuseppe

Sorry for not catching this in the first round.

What happens when we return here? Obviously this function is supposed
to never return. Should we call hang() here?

Best regards,
