I notice that this code uses pointers to return error codes. We tend
to avoid that in U-Boot and use an integer return instead, with the
pointer returned as a parameter. We have things like log_msg_ret() to
help with that. I don't have strong feelings about this if the goal is
to make the code match linux code. But if this code is for U-Boot
only, please do avoid it.

Simon
